A car travels first half distance between two places with a speed of 40 kilometre per hour and rest of half distance with a speed of 60 km per hour. The average speed of car is:

Let the total distance covered be"s" km.

Total time taken,

=(s/2)/30+(s/2)/60

=3s/120

Average speed,

=s/(3s/120)

=s(120/3s)

=40 km/hr
