A car covers a distance of 180 km in 5 hours.
(i) How much distance will the car cover in 3 hours with the same speed?
(ii) How much time will the car take to cover 54 km with the same speed?
A car covers a distance of 180 km in 5 hours.
(i) How much distance will the car cover in 3 hours with the same speed?
(ii) How much time will the car take to cover 54 km with the same speed?
(i)Given
Distance covered by car in 5 hours = 180 km
Hence distance covered by car in 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
∴ Distance covered by car in 3 hours with the same speed will be 108 km
(ii)
Given
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 taken by the car to cover 180 km distance = 5 hours
Time taken by the car to cover 1 km distance = 5 / 180 hour
Time taken to cover 54 km distance by car = 5 / 180 × 54
= 1.5 hours
∴ Time taken to cover 54 km distance by the car is 1.5 hours
(i)Given
Distance covered by car in 5 hours = 180 km
Hence distance covered by car in 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
∴ Distance covered by car in 3 hours with the same speed will be 108 km
(ii)
Given
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 taken by the car to cover 180 km distance = 5 hours
Time taken by the car to cover 1 km distance = 5 / 180 hour
Time taken to cover 54 km distance by car = 5 / 180 × 54
= 1.5 hours
∴ Time taken to cover 54 km distance by the car is 1.5 hours
