Answer:

48 km/h

Letx consider, x= total distance covered by the car,

Time taken to complete the half distance with velocity v=40km/h,

t  

1

=  

2×40

x

=  

80

x

hr. . . . .(1)

The time taken to complete another half distance with velocity u=60km/h

t  

2

=  

2×60

x

=  

120

x

hr

The total time taken, t=t  

1

+t  

2

 

t=  

80

x

+  

120

x

=  

48

x

hr

The average speed of the car,  

v  

avg

=  

x/48

x

=48km/h
