The car completes a journey of 240 km in 4 hours. If its speed is increased by 25%, how long will it take to cover a distance of 300 km?
Show answer & explanation
Correct answer: A
Explanation
Initial speed of the car = 240 ÷ 4
= 60 km/h
New speed after a 25% increase = 60 × 125/100
= 75 km/h
Time taken to cover a distance of 300 km = 300 ÷ 75
= 4 hours
