Question and options
A train is moving at a speed of 92.4 km/hr. How many metres will it cover in 10 minutes?
- 1540
- 15400
- 154
- 15.4
Answer and explanation
Correct answer: B - 15400
Ten minutes is 10/60 = 1/6 of an hour, so the train covers 92.4 ÷ 6 = 15.4 km. Since 1 km = 1,000 m, that is 15,400 m; 1,540 m and 154 m come from converting kilometres to metres with the wrong power of ten.
