The average speed for the walk would be 5 km /hr, for the run would be 15 km/hr and the average speed for the drive would be 40 km/hr.

The average speed after the walk and the run would be 7.5 km/hr

What is speed?

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second. The generally considered unit for speed is a meter per second.

average speed = total distance/total time

The average speed for the walk would be 5 km /hr, for the run would be 15 km/hr and the average speed for the drive would be 40 km/hr.

average speed during walk and run = (15+15)/ (3+1)

                                                            =7.5 km/hr

Thus, The average speed after the walk and the run would be 7.5 km/hr.
