Distance, Displacement & Average Speed

A car covers the first half of the distance between two places at 40 km/h and another half at 60 km/h. The average speed of the car is

Show answer and solution

Answer: (b)

Equal distances: $v_{avg} = \frac{2v_1 v_2}{v_1 + v_2}$ .
$v_{avg} = \frac{2(40)(60)}{100} = 48$ km/h
So the answer is (b) 48 km/h.
