The car delivered the cargo from point A to point B, moving at an average speed of 40 km / h. Returning back, the car moved at a speed of 60 km / h. Determine the average speed of the vehicle along the way.
The average speed of movement is determined in the same way as the arithmetic average:

Uav = (40 + 60) ÷ 2 = 50 km / h
Answer: Usr = 50 km / h
