Example 1 · level 1 — a gentle start
A cyclist travels at 3 km/h for 5 hours. How far do they go, in km?

- 30
- 15
- 0.6
Answer: 15 — Distance = speed × time, so speed = distance ÷ time and time = distance ÷ speed.
Speed, distance and time comes up in the maths paper of every major 11+ format. Here is what the questions look like, the method that works under time pressure, and five worked examples with the full reasoning, from a gentle start to a hard paper.

Where marks get lost: Watch the units. If the speed is in km per HOUR, the time must be in hours — not minutes.
Every question below is generated by the same engine your child practises on, and every answer is derived by our checker rather than written by hand — which is why we can put them on a public page at all.
Example 1 · level 1 — a gentle start
A cyclist travels at 3 km/h for 5 hours. How far do they go, in km?
Answer: 15 — Distance = speed × time, so speed = distance ÷ time and time = distance ÷ speed.
Example 2 · level 2 — typical of early practice
A cyclist travels at 26 km/h for 7 hours. How far do they go, in km?
Answer: 182 — Distance = speed × time, so speed = distance ÷ time and time = distance ÷ speed.
Example 3 · level 3 — standard paper difficulty
A train covers 354 km in 6 hours. What is its speed, in km/h?
Answer: 59 — Distance = speed × time, so speed = distance ÷ time and time = distance ÷ speed.
Example 4 · level 4 — a harder paper
A train covers 90 km in 9 hours. What is its speed, in km/h?
Answer: 10 — Distance = speed × time, so speed = distance ÷ time and time = distance ÷ speed.
Example 5 · level 5 — the level that separates candidates
A car travels 688 km at 86 km/h. How many hours does it take?
Answer: 8 — Distance = speed × time, so speed = distance ÷ time and time = distance ÷ speed.
