A boat can cover 220 km in downstream in 10 hours and 170 km in upstream in 17 hours. Find the distance travelled by the boat in still water in 5 hours.
The speed of Boat is given as 20 km/hr and 28 km/hr while travelling to Upstream and downstream individually.Then, the boat travelled for ‘T’ hours ...
A boat goes 52 km in Downstream in 4 hours and takes 5 hours to complete a distance of 15 km in upstream. Find the speed of boat in still water.
Speed of a boat in still water is 6 times more than the speed of stream. If boat covers 112 km in downstream in 8 hours, then find the time taken by the...
The speed of a boat in still water is 20 km/hr. If the boat covers 80 km in upstream in 8 hours, then find the time taken by the boat to travel 150 km i...
Speed of boat is 20 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 72 km downstream?
