Question

Two drivers, Alison and Kevin, are participating in a drag race. Beginning from a standing start, they each proceed with aconstant acceleration. Alison covers the last 1/4 of thedistance in 3 seconds, whereas Kevin covers the last 1/3 of thedistance in 4 seconds. Who wins and by how much time? Please show all steps and the logic to get there.

Answer 1

They arrive at the same time.

Explanation:

If Alison spends 3 seconds to cover the last 1/4, it means that in 12 seconds will cover the four quarters because the acceleration is constant.

On the other hand Kevin spends 4 seconds to cover the last 1/3 of the distance, it means that in 12 seconds will cover three thrds.

Finally we can conclude that both of them spend the same time to cover the drag race.
