Quantitative
A person covers a certain distance at a speed of 50 km/h and returns at 30 km/h. What is the average speed for the entire journey?
Let distance = D km Time forward = D/50 hours Time return = D/30 hours Total time = D/50 + D/30 = D(3+5)/150 = 8D/150 = 4D/75 hours Total distance = 2D km Average speed = 2D / (4D/75) = 2D × 75/4D = 37.5 km/h
