Answer:

48 km/hr

Explanation:

The distance- d

Speed in one direction- 60 km/hr

Speed in opposite direction- 40 km/hr

Time in one direction- t1=d/60

Time in opposite direction- t2=d/40

Average speed of the car s= 2d/(t1+t2)

t1+t2= d/60+d/40= 5d/120=d/24

s=2d/d/24=2*24=48 km/hr

Average speed of the car is 48 km/hr
