#### Question No 8

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:

Solution!
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
.
