Question

A truck covers a certain distance in 14 hours at the speed of 62km/ hr what is the average speed of a car which travels a distance of 280 km more than the truck in the same time

Answer 1

Given :
Speed of truck=V=62km/hr
Time taken by truck=14hrs
Distance =?
Distance= Speed X time               
=62x14               
 =868m

Average Speed of car=?
Distance travelled by car is =280+868=1148m
Time=14hrs
Average Speed= total distance/ Total time                       
    =1148/14                         
 =82km/hr

Therefore Average speed of car=82km/hr
