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
