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?

Time taken by car to reach destination at 60 km/hr = 2 hours
We know, Distance = Speed × Time
∴ Distance travelled = 60 × 2 = 120 km.
∴ Time taken by car to reach destination at 80 km/hr = 120/80 = 1.5 hours
