The speed of a boat downstream is 20% more than the speed of the boat in still water. If the boat can travel 1280 km upstream in 16 hours, then find the...
Ratio of speed of boat in downstream and speed of stream is 7:3, if speed of current is 9 km/hr, then find distance travelled (in km) upstream in 6 hours.
A man can row at 2 kmph in still water. If the velocity of current is 1 kmph and it takes him 4 hour to row to a place and come back, how far is the place?
The speed of current is 5 km/h. What will be the respective downstream speed and upstream speed of a boy rowing a boat, if half of the distance covered ...
A boat can cover 84 km upstream and 252 km downstream in 14 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
