01.  The rate of a stream is 4 kmph. A boat goes 6 km and back to the starting point in 2 hours. What is the speed of the boat in still water?  

02.  A man can row upstream at 8 kmph and downstream at 13 kmph. The speed of the stream is  

03.  Anand can row 20 km in 2 hours in still water. If the speed of the stream is 6 kmph, he would take 3.75 hours to cover a round trip journey. Find the distance that he would then cover each way.  

04.  Anand can row a boat in still water at a speed of 5 kmph. The speed of the stream is 3 kmph. Find the time taken by him to row 40 km downstream (in hours).  

05.  A man rows at the rate of 5 kmph in still water. If the river runs at the rate of 1.5 kmph, it takes him 1 hour to row to a place and back. What is the distance?  

06.  In one hour, A boat goes 11 kms along the stream and 5 kms against the stream. The speed of the boat in still water is  

07.  In a certain time, a boat can cover either a certain distance upstream or 5/2 times that distance downstream. If the speed of the current is 6 kmph, find the speed of the boat in still water.  

08.  A boat running downstream covers a distance of 16 kms in 2 hrs while for covering the same distance upstream, it takes 4 hrs. What is the speed of the boat in still water?  

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

10.  A boat man goes 2 kms against the current of the stream in1 hour and goes 1 km along the current in 10 mins. How long will it take to go 5 km in stationary water?
