the average speed is given by total distance divided by total time to calculate the distance in east direction we multiply 15 metre per second with 2 seconds it comes 30 metre towards east and in second case we get distance equal to 40 metre now Total distance equal to 70 metre. now average speed equal to 70 / 10 equal to 7 metre per second
