Explanation:

3 hours 45 minutes = =

11. A person takes 20 minutes more to cover a certain distance by decreasing his speed by . What is the time taken to cover the distance at his original speed?

A. 1 hour 30 minutes

B. 1 hour 15 minutes

C. 1 hour 20 minutes

D. 2 hours

E. 1 hour 45 minutes

Ans: C

Explanation:

Let the distance and original speed be d km and k kmph respectively.

Time taken to cover the distance at original speed.

1 hour 20 minutes.

12. Kiran travels from A to B by car and returns from B to A by cycle in 7 hours. If he travels both ways by car he saves 3 hours. What is the time taken to cover both ways by cycle?

A. 10 hours

B. 13 hours

C. 14 hours

D. 12 hours

E. None of these

Ans: A

Explanation:

Let the time taken to cover from A to B in car and cycle be x hours and y hours respectively.

Solving both the equations, we get

So, time taken to cover both ways by cycle =2y hours=10 hours.

19. Ramu rides his bike at an average speed of 45 km/hr and reaches his destination in four hours. Somu covers the same distance in six hours. If Ramu covered his journey at an average speed which was 9 km/hr less and Somu covered his journey at an average speed which was 10 km/hr more, then the difference in their times taken to reach the destination would be (in minutes).

A. 36

B. 30

C. 40

D. 45

E. None of these.

Explanation:

Distance travelled by Ramu =km

Somu travelled the same distance in 6 hours.

His speed =

Hence in the conditional case, Ramu’s speed =-km/hr and Somu’s speed=

Therefore travel time of Ramu and Somu would be 5 hours and hours

Respectively.

Hence difference in the taken= hours= minutes.
