A car travels first half distance between two places with a speed of 40 km/hr and rest of the half distance with a speed of 60 km/hr. The average speed of the car is ?

A. 48 km/hr

B. 37 km/hr

C. 44 km/hr

D. 45 km/hr

Answer : A. 48 km/hr

Explanation :

Let the total distance covered be S km.
Total time taken= S / (2 × 40) + S / (2 × 60)
= 5S / 240 hr
Average speed = S × ( 240/ 5S )
= 48 km/hr
