Question

. A motorcyclist drives from A to B with a uniform speed of 40 km/h and returns back with a speed of 50 km/h. Find his average speed and average velocity

Answer 1

Answer:

The average of the body is total distance/total time and the Velocity is change in displacement/time

Speed is -20km/hr and velocity is zero

Explanation:

The speed from A to B=40km/hr

The speed from B to A=50km/hr

Average speed =Distance/time

40km/hr-50km/hr=2d/t

-10km/hr=2d/t

-20km/hr=d/t

Average velocity is zero as the body returns to the same place
