Question
A car running with a speed of 55 km/hr takes 12 hours to
go from 'A' to 'B'. If on the way back from 'B' to 'A', the car takes 20% less time than it takes while going from 'A' to 'B', then find the approximate average speed of the car during the whole journeySolution
Total distance covered by the car in 12 hours = 55 x 12 = 660 km Time taken by the car in the return journey = 0.80 x 12 = 9.6 hours Average speed = Total distance covered ÷ Total time taken Average speed of the car = (660 x 2) ÷ (12 + 9.6) ~ 61.1 km/h
