Question

A car takes 2 hours to reach a destination by travelling at the speed of 60 km/h. How long will it take when the car travels at the speed of 80 km/h ?

Answer 1

Answer:

1(1/2) hours

Step-by-step explanation:

Let car takes x hours.

If the speed of car increases, then the time taken to reach a destination will decrease. Hence, it is a case of inverse proportion.

So,

==> x * 80 = 2 * 60

==> 80x = 120

==> x = 3/2

==> x = 1(1/2) hours

Hence, the car will take 1(1/2) hours to reach its destination.
