A car covered 240 km in 5 h. If it travels with half of its usual speed, then how much more time will be taken to cover the same distance?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 5 h.
Given that
A car covered 240 km in 5 h
The speed of the car = 240/5 = 48 km/h
Now, it travels at half of its usual speed = 48/2 = 24km/h
The time will be taken to cover the same distance = 240/24 = 10 h
Hence, 5 h more time will be taken.
