Question

The distance between two places is 120 km. A car travelling at a certain speed can cover
the distance in 2 hours 30 minutes. By how many km/h should the speed of the car be
increased for it to take 30 minutes less to cover the distance?​

Answer 1

Answer:

Your answer :

Here, distance =120km and time=2hr30min

So, speed = distance/ time

Average speed = 120/ 2.5 because 2hr30min = 2.5 hrs

120/2.5= 48km/h

Now, 2hr30min - 30min = 2hrs

So, 120/2 = 60km/h »»» (60–48)km/h = 12km/h

This is the correct answer according to the question..
