Answer 1

Answer:

80 km / hr

Step-by-step explanation:

Given Sujeet covers a distance in 40 minutes if he drives at a speed of 60 km/h on an average . find the speed at which he must drive to reduce the time of journey by 25%

We know the speed is 60 km / hr . It means he covers a distance of

60 km in 60 min. So in 40 min Sujeet covers a distance of 40 km.

Since speed is reduced by 25%, it will be 25 / 100 x 40  = 10. So 40 - 10 = 30 min

30 min = 1/2 hr

Now speed = distance / time

        speed = 40 / 1/2

 So speed = 40 x 2 = 80 km / hr
