A car can cover 275 km in 5 hours. If its speed is reduced by 5 km/h, then how much time will the car take to cover a distance of 300 km?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 6 hours.
The original speed of the car = Distance/Time = 275/5 = 55 km/h
New speed after reduction = 55 − 5 = 50 km/h
Time taken to cover 300 km at the new speed = Distance/Speed = 300/50 = 6 hours
The car will take 6 hours to cover 300 km.
