If anshul rows 15 km upstream and 21 km downstream taking 3 hours each time, then the speed of the stream is
A man rows to a place 48 km distant and come back in 14hours.
He finds that he can row 4 km with the stream in the same time as 3 km against thestream.
The rate of the stream is
A man rows 13 km upstream in 5 hours and also 28 km downstream in 5hours.
The velpciy of the stream is
Excluding stopages, the speed of a bus is 54 kmph and including stopages, it is 45kmph.
For how many minutes does the bus stop per hour
A man's speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is
In a 4000 meter race around a circular stadium having a circumference of 1000 meters, the fastest runner and the slowest runner reach the same point at the end of the 5th minute, for the first time after the start of therace.
All the runners have the same staring point and each runner maintains a uniform speed throughout therace.
If the fastest runner runs at twice the speed of the slowest runner, what is the time taken by the fastest runner to finish the race
4. 5 min
2 trains starting at the same time from 2 stations 200km apart and going in opposite direction cross each other at a distance of 110km from one of thestations.
What is the ratio of their speeds

Robert is travelling on his cycle and has calculated to reach point A at 2 P.M. if he travels at 10 kmph, he will reach there at 12 noon if he travels at 15kmph.
At what speed must he travel to reach A at 1 P.M
A 100 meter long train is running at the speed of 30 km/hr. Find the time taken by it to pass a man standing near the railway line
A boat covers a certain distance downstream in 1 hour, while it comes back in 1hours.
If the speed of the stream be 3 kmph, what is the speed of the boat in still water
A snail is at the bottom of a 20 meters deeppit.
Every day the snail climbs 5 meters upwards, but at night it slides 4 meters backdownwards.
How many days does it take before the snail reaches the top of the pit
Two boys starting from the same place walk at a rate of 5 kmph and 5.5 kmphrespectively.
What time will they take to be 8.5 km apart, if they walk in the same direction
If a man runs at 3 m/s. How many km does he run in 1hr 40min
Two trains travel in opposite directions at 36 kmph and 45 kmph and a man sitting in slower train passes the faster train in 8seconds.
Then length of the faster train is
A boat covers 24 km upstream and 36 km downstream in 6 hours while it covers 36 km upstream and 24 km downstream in 6hours.
The velocity of the current is
A boat takes 90 minutes less to travel 36 miles downstream than to travel the same distanceupstream.
If the speed of the boat in still water is 10 mph, the speed of the stream is
A man can row at 5 kmph in stillwater.
If the velocity of current is 1 kmph and it takes him 1 hour to row to a place and come back, how far is the place
In a 500 m race, the ratio of the speeds of two contestants A and B is 3 : 4. A has a start of 140 m. Then, A wins by
Two goods train each 500 m long, are running in opposite directions on paralleltracks.
Their speeds are 45 km/hr and 30 km/hrrespectively.
Find the time taken by the slower train to pass the driver of the faster one
