Question 1:

A man can row $30 \mathrm{~km}$ upstream in 6 hours. If the speed of the man in still water is $6 \mathrm{~km} / \mathrm{hr}$, find how much he can row downstream in 5 hours.

Question 2:

A man takes 2 hours to swim 25 km downstream. He swims 19 km upstream in the same time. What is the speed (in km/hr ) of the current ?

Question 3:

Speed of a boat along the current and against the current are $10 \mathrm{~km} / \mathrm{hr}$ and $8 \mathrm{~km} / \mathrm{hr}$ respectively. What is the speed of boat (in $\mathrm{km} /$ $\mathrm{hr}$ ) in still?

Question 4:

A boat goes 70km downstream in 14 hours and a distance of 48km upstream in 12 hours. Find the speed of the stream. (In kmph )

Question 5:

A man can row 30 km upstream and 44 km downstream in 10 hours. It is also known that he can row 40 km upstream and 55 km downstream in 13 hours. Find the speed of the stream in still water.

Question 6:

A motor boat has speed $30 \mathrm{~km} / \mathrm{h}$ in still water. It goes $60 \mathrm{~km}$ down stream and comes back in $\frac{9}{2}$ h. What is the speed of the stream?

Question 7:

The time taken by a boat to row 21 km with the stream is same as the time taken by it to row 12 km against the stream. If the speed of boat in still water is 5.5 kmph, find speed of stream?

Question 8:

A boat can go 10 km upstream and 11 km downstream in a total time of 52 minutes. If the speed of the stream is 5 km/h, then what is the speed (in km/h ) of the boat when going downstream ?

Question 9:

vikrant can row a boat $24 \mathrm{~km}$ upstream in 1 hour 12 minutes. If the speed of the current of the river is $1.5 \mathrm{~km} / \mathrm{h}$, then how much time will he take to row the boat $57.5 \mathrm{~km}$ downstream?

Question 10:

A swimmer can swim at a speed of 12 km/h in still water. If a river is flowing at a speed of 2 km/h, then how much time will the swimmer take to swim 6 km upstream?
