A car has to cover a distance of 288 km in 20 hours. If it covers half of the journey in 1/5 th of the time, find the speed to cover the remaining distance in the time left.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 9 km/hr
Given that
A car has to cover a distance of 288 km in 20 hours.
It covers half of the journey in 1/5 th of the time,
According to the question
The car travels half distance = 288/2 = 144 km, in 20/5 = 4 hours
So, the remaining distance = 288 - 144 = 144 km
The remaining time = 20 - 4 = 16 hours
Hence, the speed of car for covering the remaining distance = 144/16 = 9 km/h
