Question

Jane starts driving her car down the road at 30 miles per hour. At the same time, the local train starts going down the tracks. The train is going 35 miles per hour, a little bit faster than Jane's car. After two hours, which will cover the greater distance, the train or the car?

Answer 1

answer : train because it has a greater speed compared to the car and it travels for the same amount of time,so train will cover greater distance

Answer 2

This question tries to compare speeds and distance covered within a given time .

The following formula is relevant:

Speed = Distance/Time and therefore ;

Distance = Time × Speed

We can calculate the distance covered by both the train and Jane separately.

Distance covered by the train is as follows :

Distance = 35 × 2 = 70 miles

The distance covered by Jane in 2 hours is as follows :

Distance = 30 × 2 = 60 miles

From the calculations above we see that the train covers a larger distance at the same time.

This is because it is travelling at a greater speed than the car.
