# Assignment On Streams

**SOME PROBLEMS ON STREAMS**

1.Speed of a man is 7 km/hr in still water. If the rate of current is 2 km/hr, find the effective speed of the man upstream.

2.Speed of a man is 9 km/hr in still water. If the rate of current is 5 km/hr, find the effective speed of the man upstream.

3.If a man goes upstream at 6 km/hr and the rate of stream is 2 km/hr, then the man’s speed in still water is.

4.If a boat goes 12 kms upstream in 48 minutes. The speed of stream is 2 km/h. the speed of boat in still water is.

5.The speed of a boat in still water is 12 km per hour. Going downstream it moves at the rate of 19 km per hour. The sped of the boat against the stream is _____ km/hr.

6.A man can row 15 km downstream in 3 hours and 5 km upstream in 2½ hours. His speed in still water is _____ km/hr.

7.A person rows a kilometer down the stream in 10 minutes and upstream in 30 minutes. Find the velocity of the stream.

8.A man can row three quarters of a km against the stream in 11 minutes 15 seconds and return in 7 minutes 30 seconds. Find the speed of the man in still water and also the speed of the stream.

9.A man can row at the rate of 3.5 km/hr in still water. If the time taken to row a certain distance upstream is 2½ times as much as to row the same distance downstream, find the speed of the current.

10. A man can row 4 km/hr in still water and he finds that it takes him twice as long to row up as to row down the river. Find the rte of stream.
