A car travels up a hill at a constant speed of 40 km/h and returns down the hill at a constant speed of 60 km/h. average speed=distance traveled/time traveled. How does physics help in developing computer games? the time taken to go up the hill is t1 = d/40 (hours), the time taken to down the hill is t2 = d/60 (hours), the time T for the round trip is T = t1 + t2 = d(1/40 + 1/60) = d ((3+2)/120) = 5d/120 = d/24 (hours), the average speed is 2d/T = 2d/(d/24) = 48 (km/h). RE: a thank you to define customary velocity? What is the average speed?
