Two cars are travelling in the same direction, on a motorway. Car A is travelling at 20m/s and Car B is travelling at 30m/s. It takes 30 seconds for Car B to overtake Car A, How much further does car B travel during this time? ( I need the answer and the calculation please )

300 m

Explanation:

For an object travelling with uniform motion (=constant velocity), the distance covered by the object is given by the equation:

where

d is the distance covered

v is the speed of the object

t is the time elapsed

In this problem we have:

- For Car A,

v = 20 m/s (speed)

t = 30 s

So the distance covered by car A is

- For car B,

v = 30 m/s

t = 30 s

So the distance covered by car B is

So during this time, the additional distance covered by car B is
