Question

A car, covers a distance of 180 km in 5 hours.
1)How much distance will the car cover in 3 hours with the same speed ?
2)How much time will the car take to cover 54 km with the same speed ?

​

Answer 1

Answer:

1 Distance covered by car in 5 hours =180 km

Hence distance covered by car is 3 hours can be calculated as below

Distance covered by car in 1 hour =180/5

=36 km

Distance covered by car in 3 hours =36×3

=108 km

2∴ Distance covered by car in 3 hours with the same speed will be 108 km

Distance covered by car in 5 hours =180 km

Hence time taken by the car to cover 54 km distance can be calculated as below

Time is taken by the car to cover 180 km distance =5 hours

Time is taken by the car to cover 1 km distance =5/180 hour

Time taken to cover 54 distance by car =5/180×54

=1.5 hours

∴ Time taken to cover 54 km distance by the car is 1.5 hours
