# Speed Distance and Time Questions with Answers: Download PDF > Fifteen speed distance and time questions with answers, including trains and relative speed, each worked in consistent units. Free PDF, no sign-up needed. Source: https://computeprep.com/questions/speed-distance-time --- ## Speed distance and time questions with answers Speed distance and time questions are three-quarters unit discipline. Most wrong answers on this family are correct arithmetic on a kilometre-per-hour figure that should have been metres per second. Each walkthrough below converts first and computes second, and states the conversion it used rather than assuming it. [Download the PDF — 15 questions with answers](https://computeprep.com/questions/speed-distance-time.pdf) Free, ungated, no email. This is the speed distance time questions with answers PDF — the same 15 questions as below, with every worked solution at the back, ready to print. ### How to use this set The 15 questions below are ordered the way an exam block is rather than easiest-first: two gentle openers, then a run of medium, and a hard one every sixth question — 2 of the 15 sit in the hard band. Every question is a time, speed & distance. Work each question on paper before you open its solution. The walkthrough is the method itself, step for step, so reading it first turns a practice set into a reading exercise and teaches nothing. If you are stuck on the method rather than on one question, the method guide is a better place to start than the next question: [Speed, distance and time: units first](https://computeprep.com/drill-types/speed-distance). ### 15 speed distance and time questions with answers Every question below was generated by the same engine that mints the ComputePrep daily timed drill, and machine-checked before it reached this page — a multiple-choice question validates its own answer against its own options at generation, and ships only with a walkthrough attached. The walkthrough is the engine's own. #### Question 1 How far does it travel? A train runs at a steady 72 km/h for 4 hours. - 288 - 72 - 283 - 76 - 18 - Distance = speed × time = 72 × 4 = 288 km. - Answer: 288 km. #### Question 2 How far does it travel? A train runs at a steady 30 km/h for 5 hours. - 156 - 150 - 180 - 157 - 35 - Distance = speed × time = 30 × 5 = 150 km. - Answer: 150 km. #### Question 3 How long does the journey take? A train covers 640 km at a steady 80 km/h. - 9 - 16 - 560 - 8 - 80 - Time = distance ÷ speed = 640 ÷ 80 = 8 hours. - Answer: 8 hours. #### Question 4 How far does it travel? A train runs at a steady 30 km/h for 8 hours. - 270 - 240 - 38 - 252 - 243 - Distance = speed × time = 30 × 8 = 240 km. - Answer: 240 km. #### Question 5 How far does it travel? A train runs at a steady 30 km/h for 5 hours. - 6 - 180 - 150 - 35 - 30 - Distance = speed × time = 30 × 5 = 150 km. - Answer: 150 km. #### Question 6 What is its average speed for the whole journey? A car covers a certain distance at 20 km/h and returns along the same route at 60 km/h. - 30 - 80 - 19 - 40 - 15 - Equal distances, different speeds — the average is HARMONIC, not the plain mean. - Average = 2 × 20 × 60 ÷ (20 + 60) = 2400 ÷ 80 = 30 km/h. - The tempting 40 km/h is wrong: more time is spent on the slower leg. - Answer: 30 km/h. #### Question 7 How long does the journey take? A train covers 280 km at a steady 40 km/h. - 40 - 14 - 7 - 8 - 240 - Time = distance ÷ speed = 280 ÷ 40 = 7 hours. - Answer: 7 hours. #### Question 8 How long does the journey take? A train covers 360 km at a steady 40 km/h. - 9 - 2 - 320 - 0 - 7 - Time = distance ÷ speed = 360 ÷ 40 = 9 hours. - Answer: 9 hours. #### Question 9 What is its average speed for the whole journey? A car covers a certain distance at 10 km/h and returns along the same route at 40 km/h. - 16 - 30 - 50 - 26 - 25 - Equal distances, different speeds — the average is HARMONIC, not the plain mean. - Average = 2 × 10 × 40 ÷ (10 + 40) = 800 ÷ 50 = 16 km/h. - The tempting 25 km/h is wrong: more time is spent on the slower leg. - Answer: 16 km/h. #### Question 10 How long does the journey take? A train covers 80 km at a steady 40 km/h. - 2 - 5 - 0 - 1 - 40 - Time = distance ÷ speed = 80 ÷ 40 = 2 hours. - Answer: 2 hours. #### Question 11 How long does the journey take? A train covers 90 km at a steady 30 km/h. - 4 - 3 - 30 - 6 - 60 - Time = distance ÷ speed = 90 ÷ 30 = 3 hours. - Answer: 3 hours. #### Question 12 What is its average speed for the whole journey? A car covers a certain distance at 20 km/h and returns along the same route at 60 km/h. - 22 - 21 - 30 - 16 - 40 - Equal distances, different speeds — the average is HARMONIC, not the plain mean. - Average = 2 × 20 × 60 ÷ (20 + 60) = 2400 ÷ 80 = 30 km/h. - The tempting 40 km/h is wrong: more time is spent on the slower leg. - Answer: 30 km/h. #### Question 13 How long does the journey take? A train covers 216 km at a steady 72 km/h. - 1 - 144 - 2 - 3 - 0 - Time = distance ÷ speed = 216 ÷ 72 = 3 hours. - Answer: 3 hours. #### Question 14 How far does it travel? A train runs at a steady 30 km/h for 9 hours. - 3 - 30 - 300 - 39 - 270 - Distance = speed × time = 30 × 9 = 270 km. - Answer: 270 km. #### Question 15 How far does it travel? A train runs at a steady 50 km/h for 5 hours. - 10 - 250 - 300 - 55 - 263 - Distance = speed × time = 50 × 5 = 250 km. - Answer: 250 km. ### Where these questions come from Most free practice for this topic is a scanned upload or a blog quiz, and neither can tell you a question has exactly one answer. That is the one thing this set can promise: it is minted, not typed. The engine behind it serves ComputePrep's daily timed drill, so the questions here are the same shape as the ones a live round would give you — and there is an unlimited supply of them, which is why this page can be regenerated rather than padded. If you want the method rather than more questions, [Speed, distance and time: units first](https://computeprep.com/drill-types/speed-distance) covers the approach, the traps and a worked table. This page and that one deliberately answer different questions: that one is *how do I solve these*, this one is *give me speed distance and time questions with the answers*. ### FAQ #### What is the conversion between km/h and m/s? Multiply by 5/18 to go from km/h to m/s, and by 18/5 to go back. Any question involving a train passing a pole, a platform or another train needs metres per second, and doing that conversion before anything else removes the most common error in the family. #### How does relative speed work for two trains? Add the speeds when they move towards each other or in opposite directions; subtract when they move the same way. The distance covered is the sum of both lengths when one train passes another, and just the train's own length when it passes a pole. #### What is the average speed for a round trip? Not the average of the two speeds — it is the harmonic mean, 2ab/(a + b), because equal distances take unequal times. At 40 and 60 km/h the average is 48, not 50. The arithmetic mean is always among the options, so the distinction is worth holding firmly. ### More question banks - [Time and work questions with answers](https://computeprep.com/questions/time-and-work) — 15 worked questions and a PDF. - [Square root and cube root questions with answers](https://computeprep.com/questions/square-root-and-cube-root) — 15 worked questions and a PDF. - [Simple and compound interest questions with answers](https://computeprep.com/questions/simple-and-compound-interest) — 15 worked questions and a PDF. - [All drill types](https://computeprep.com/drill-types) — the method guides behind every bank.
