If a man rows at the rate of 5 kmph in still water and his rate against the current is 3.5 kmph, then the man's rate along the current is : `4. 25\ k m p h` b. `6\ k m p h` c. `6. 5\ k m p h` d. `8. k m p h\ `

A man's speed with the current is 15 km / hr and the speed of the current is 2.5 km/ hr. The man's speed against the current is: 8. 5\ k m//h r b. \ 9\ k m//h r c. 10\ k m//h r d. 12. k m//h r

A man can row upstream at 10 kmph and downstream at 18 kmph. Find the man's rate in still water? 14\ k m p h b. 4\ k m p h c. 12\ k m p h d. 10\ k m p h

A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 1 hour to row to a place and come back, how far is the place? 2. 4 k m b. 2. 5 k m c.3 k m d. 3. 6 k m

A man can row 5 km/h in still water. If the rate of current is 1 km/h, it takes 5/4 hours to row to a place and back. How far is the place?

A man rows to a place 48 km distant and back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is : 1 k m//h r b. 1. 8 k m//h r c. 1. 5 k m//h r d. 3. 5 k m//h r
