Question

a car takes 7hrs to cover a certain distance at the speed of 48 km per hour if the speed is decreased by 20 km per hour how much time will it take to cover the same distance?​

Answer 1

Answer:

See distance=speed×time

7×48=336km is the distance

now speed=28km/hour

now time=distance/time

=336/28

=12hour

so the car will take 12 hours to cover the same distance

hope its help u dear
