Question 1
Speed of boat in still water is 4 times to speed of current. If a person covers 60 km in 10 hrs in upstream then what is speed of boat in still water?
Question 2
A steamer covers 80 km in 4 hrs in still water. If speed of boat is 50% more than that of stream then time required for steamer to cover this distance in upstreem?
Question 3
A river rafting course is 30km long, and the stream is moving at an average of 4 km/h. Boat ‘A’ takes a total of 4 hr to go up and down stream. Boat ‘B’ takes 40 minutes more than boat ‘A’ to do the same. What is the difference between the speeds of 2 boats?
Question 4
Kuntal can row to a place distance of 60 km and return in 37.5 hours. He can row 32 km in downstream and 8 km in upstream in equal time. What is the rate of the stream?
Question 5
A boat can go 8 km in still water in 1 hour but it takes 3 hours to travel the same distance upstream. Find the speed of the stream.
Question 6
The speed of a boat in still water is 16 kmph and the rate of current is 5 kmph. Find the distance travelled by the boat in downstream in 30 minutes duration.
Question 7
A boat can travel 15 km downstream in 18 min. The ratio of the speed of the boat in still water to the speed of the stream is 4 : 1. How much time will the boat take to cover 10 km upstream?
Question 8
Anil can swim a certain distance downstream in 6 hours and return the same distance in 9 hours. If the stream flows at the rate of 
per hour, find how far he can swim in an hour in still water?(km)
per hour, find how far he can swim in an hour in still water?(km)Question 9
The ratio of the downstream speed of a boat to the upstream speed is 40:7. If the boat goes somewhere along the flow of the river in 5 hours, how long will it take to travel the same distance in the against the flow of river?
Question 10
A man can row 
kmph in still water. If in a river running at 1.5 km an hour, it takes him 50 minutes to row to a place and back, how far off is the place ?
