A boat goes 52 km in upstream in 4 hours and takes 3 hours to complete a distance of 21 km in downstream. Find the speed of boat in still water.
A submarine can travel a certain distance downstream in 4 hours and the same distance upstream in 8 hours. If the submarine's speed in still water is 12...
Speed of a boat in still water to speed of boat in upstream is 7:5. If the boat can travel 360 km in downstream in 5 hours, then find the time taken by ...
The speed of current is 8 km/h. What will be the respective downstream speed and upstream speed of a boy rowing a boat, if one fifth of the distance cov...
Find the total distance covered by boat in each upstream and downstream in 5 hours if the speed of boat in still water and speed of current is 25 km/h a...
A boat can cover 140 km in downstream in 14 hours and 96 km in upstream in 12 hours. Find the distance travelled by the boat in still water in 5 hours.
The speed of a boat in still water is 35 km/hr. If the boat covers 150 km in upstream in 5 hours, then find the time taken by the boat to travel 200 km ...
