Answer:

3 m/s east

Step-by-step explanation:

The velocity of the car is given by:


v=(d)/(t)

where

d is the displacement

t is the time taken

The displacement of the car does not depend on the path of the car, but just on it the difference between its final position and its starting position, so it is equal to 15 metres east. The time taken is 5 seconds, therefore the velocity is equal to


v=(15 m)/(5 s)=3 m/s

and the direction is east.
