Solution:
According to the question:
Time is taken by Sumit to cover the distance of 384 km with the speed of x = Time taken by Sumit to cover the distance of 324 km with the speed of 15 m/s.
Question.4
If the difference between the speed of Saurabh and Sanjay is 55 km/h and time taken by both is 14 km to cover the given distance. What will be time taken by Sanjay to cover the distance of 250 km.A. 6.25 hour
B. 5 hour
C. 5.25 hour
D. 7.5 hour
E. None of these
Ans. A.
Solution:
= 95km/h.
Time taken by Saurabh is given that is 4 hours.
So time taken by Sanjay is 10 hours.
If the Speed is 95+55 = 150 km/h
Then distance = 150×10 = 1500 km.
But this is not possible because the distance travel by Sunil and Sanjay is 1100 km.
If the distance is 9555 = 40 km/h
Then distance = 40×10 = 400 km.
So the speed is 40 km/h
Time taken to cover the distance of 250 km = 250/40
= 6.25 hour
