A boat travels 48 km downstream in 4 hours and 24 km upstream in 6 hours. What is the speed of the boat in still water?
A boat can cover ‘y’ km distance downstream in (t+2.5) hours. The same boat can cover ‘0.25y’ km distance upstream in ‘t’ hours. The time ta...
The speed of a boat in still water is 12 times the speed of the stream. If the difference between the upstream and downstream speed of the boats is 20 k...
A man can row at 3 kmph in still water. If the velocity of current is 2 kmph and it takes him 6 hour to row to a place and come back, how far is the place?
A man rows a boat a certain distance downstream in 9 hours, while it takes 18 hours to row the same distance upstream. How many hours will it take him t...
The downstream speed of a boat is 75% greater than its upstream speed, and the speed of the stream is 3 m/s. How far can the boat travel in still water ...
Two boats X and Y start towards each other from two places, 76 km apart. Speed of the boat X and Y in still water are 8 km/hr and 11 km/hr respectively....
Two boats A and B start towards each other from two places,108km apart. The speeds of boats A and B in still water are 12km/h and 15km/h respectively. i...
Ratio of speed of boat in downstream and speed of stream is 5:3, if speed of current is 9 km/hr, then find distance travelled (in km) upstream in 8 hours.
Speed of current is equal to 25% of speed of boat in still water. If the boat takes 5 hours to cover 120 km in still water, then find the time taken by ...
