Question 1:

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

Question 2:

Prakash can row a distance of 1250 meters in still water by boat in 10 minutes. He takes twice the time to row the boat against the stream than in the downstream. Find the speed of the stream.

Question 3:

If the speed of stream is 20% of the speed of boat in still water and it covers 120km upstream in 150 minutes , then what is the downstream speed of boat ?

Question 4:

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

Question 5:

A man covers a certain distance in Downstream and come back to starting point in Upstream and takes total 32 hours . If speed of man in still water is 8 km/h and speed of current is 5 km/h then find the distance between both point .

Question 6:

Down stream speed of boat is 14 km/h. Upstream speed of boat is 10 km/h. In how much time can it cover 72 km in still water?

Question 7:

A person rows upstream a distance of 65 km in 5 hours and rows downstream a distance of 57 km in 3 hours. How much time will he take to row a distance of 72 km in still water?

Question 8:

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

Question 9:

A motor boat has speed 30 km/h in still water. It goes 60 km down stream and comes back in 92 h. What is the speed of the stream?

Question 10:

Ratio between speed of boat in still water to speed of stream is 7:3. In downstream, boat can cover 180 km in 4 hours, then find the difference between speed of boat in still water and speed of stream.
