A. 2km/hr

B. 3km/hr

C. 5km/hr

D. cannot be determined

Ans: A

Explanation:

Let the speed in return journey be x km/hr, then

Hence the speed in return journey is 2km/hr

15. A takes 2 hours more than B to walk D km. If A doubles his speed then he can make it in 1 hour less than B. How much time does B require for walking D km?

A. D/2 km

B. 3hrs

C. 4hrs

D. 2D/3hrs

Ans: C

Explanation:

Suppose B takes x hours to walk d km

Then A takes hours to walk d km

With double of the speed.

A will take hours

Therefore,

Hence B takes 4 hours to walk d km

Explanation:

Suppose B catches A after x hours then,

Distance between travel by A in (x+4)hours = Distance travelled by B in x hours

Distance travelled by B in hrs

km = km = km

20. An express train travelled at an average speed of 100km/hr stopping for 3 minutes after 75km. A local after travelled at a speed of 50 km/hr, stopping for 1 minute after every 25km. If the trains began travelling at the same time how many km and did the local train travel in the time it took the express train to travel 60 km?

A. km

B. 900km

C. 1000km

D. 1200km

Ans: A

Explanation:

Time taken by express train to cover 75km plus stoppage =min + 3 min = 48 min

Time taken by express train to cover 600km

Time taken by local train to cover 25km plus stoppage min + 1 min = 31 min

In 31 min distance covered by = 25km

In min distance covered =km = 300km

In last 9 min distance covered = km = min

Total distance covered = km
