A car covers a particular distance in 3 hours with the speed of 54km/h. If the speed is increased by 27km/h, the time taken by the car to cover the same distance will be:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 2 hr.
We know that
Speed = Distance/Time
Now, According to the question
Total distance travelled by car = 54 × 3 = 162 km
Total increased speed = 54 + 27 = 81 km/h
New Time required,
⇒ T = 162/81 = 2h
Thus,
The time taken by the car to cover the same distance will be 2 hours.
