A car travels from town A to town B at an average speed of 60 km/hr and returns from town B to town A at an average speed of 40 km/hr. What is the average speed for the entire trip?
A.50 km/hr
B.52 km/hr
C.48 km/hr✓ Correct
D.45 km/hr
Explanation
For a round trip with equal distances, average speed = 2×S1×S2/(S1+S2) = 2×60×40/(60+40) = 4800/100 = 48 km/hr.
