An athelete runs 400 m in 20s. Calculate the average speed of the athlete.

A car moves along a straight path with variable velocity as shown in the figure. When the car is at possiting A, its velocity is 10 m s^(-1) and when it is at position B, its velocity is 20 m s^(-1) . If the car takes 5 seconds of time to move from A to B, find the acceleration of the car.
