Verified Answer :

The zebra is stationary(not moving) when the gradient of the distance/time graph is zero; between 20 and 40 seconds. The zebra is moving away from the origin when the gradient is positive; between 0 and 20 and 40 and 60 seconds. Average speed is the distance travelled/ time elapsed so the average speed is 280/60 = 4.67 m/s
