Question

4. Car A travels 100m in 5 seconds. If car B travels the same distance in 2

seconds, which one is travelling at the faster speed? Explain your answer.

Answer 1

Car B is travelling at the faster speed.

Explanation:

Given that,

The distance covered by car A = 100 m

Time of car A, t = 5 s

The distance covered by car B = 100 m

Time of car B, t = 2 s

We need to find which one is travelling at the faster speed.

Speed = distance/time

For car A,

`v_A=(100\ m)/(5\ s)\\\\v_A=20\ m/s`

For car B,

`v_B=(100\ m)/(2\ s)\\\\v_B=50\ m/s`

So, car B is travelling at the faster speed.
