Question

Q. 25 Mohan completes a journey of 320 km in 4 hours in a car. If he covers the first three fourth of the journey at 60 kmh, find the speed
the car for the balance of the journey.​

Answer 1

Answer:

Step-by-step explanation:

Total distance = 320 km

Total time = 5 hrs

Speed for 3/4 of journey = 60 km/h

3/4 of 320 = 240 km

Time taken to cover this distance = 240/60 = 4 hrs

Time left = 5-4 = 1 hrs

So distance left = 320-240 =120 km

So speed for rest of journey = distance / time = 120/1 = 120km/h
