Wipro Company Numerical Ability Time Distance and Speed

Walking 5/6 of its usual speed, a train is 10min late. Find the usual time to cover the journey?

Read Solution (Total 3)

If t is normal time with normal speed, then
with 5/6 of its usual speed, the time taken will be t*6/5.
t*6/5 -t = 10
t/5 = 10
t= 50 mins

short cut:
5/6 of u.s = 6/5 of u.t
6/5=1+1/5
so 1/5 of u.t=10 min
u.t= 50 min

Ans:50 min

Explanation: New speed = 5/6 of usual speed
New time = 6/5 of usual time
New time = 10min
Therefore Usual time = 50min

A train running at 54 kmph takes 20 seconds to pass a platform. Next it takes 12 seconds to pass a man walking at 6 kmph in the same direction in which the train is going. Find the length of the train and the length of the platform. If a man walks at the rate of 5kmph, he misses a train by only 7min. However if he walks at the rate of 6 kmph he reaches the station 5 minutes before the arrival of the train. Find the distance covered by him to reach the station.
