A car takes 5 hours to reach a destination by travelling at the speed

1.	A car takes 5 hours to reach a destination by travelling at the speed of 60 km/hr. How long will it take when the car travels at the speed of 75 km/hr?
Answer» If the speed of the car is more, time required is less to travel. Therefore it’s inversely proportional. Let us consider the required time be x hours 5 × 60 = 75 × x x = (5 × 60) /75 = 4 ∴ 4 hours are required.

Answer»

If the speed of the car is more, time required is less to travel. Therefore it’s inversely proportional.

Let us consider the required time be x hours

5 × 60 = 75 × x

x = (5 × 60) /75 = 4

∴ 4 hours are required.
