The ratio of the speed of the boat in upstream to that of in downstream is 7:10, respectively. If the speed of the current is 12 km/h, then find the spe...
A boat takes a third time to cover a certain distance downstream compared to upstream. What is the ratio of the speed of the boat in still water to the ...
The boat's speed in still water is 20% greater than the speed of the stream. If it takes the boat 4 hours more to travel 176 km d...
A boat can cover 130 km in downstream in 10 hours and 120 km in upstream in 12 hours. Find the distance travelled by the boat in still water in 4 hours.
A boat travels 48 km against the current and 144 km with the current in a total of 9 hours. If the speed of the boat in still water exceeds the stream s...
A motorboat in still water travels at a speed of 36 km/hr. It goes 64 km upstream in 2 hours. The time taken by it to cover the same distance down the s...
Calculate the speed of a boat in still water if it travels 176 km downstream in 11 hours and returns 144 km upstream in 18 hours.
Motor boat covers a certain distance downstream in 5 hours. It covers the same distance upstream in 7(1/2) hour. If the speed of the water is 4.5 km/hr,...
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
When travelling downstream, a boat takes 6.25 hours to travel 275 km. If the speed of the stream is (4/11)th of downstream speed of the boat,...
