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?

distance = speed × time

Therefore, speed and time are inversely proportional


2 × 60 = 80 × t { t be the time required to cover a given distance at 80 km/hr}


→ t = 1.5 hr
