Boat ‘A’ can cover 240 km in still water in 12 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 4:7 and the sp...
A boat goes 65 km in upstream in 5 hours and takes 4 hours to complete a distance of 20 km in downstream. Find the speed of boat in still water.
Speed of a boat in still water is 4 times more than the speed of stream. If boat covers 126 km in downstream in 7 hours, then find the time taken by the...
A boat goes 45 km upstream in 6 hours and 60 km downstream in 4 hours. If the speed of the current is doubled, how much time will the boat take to trave...
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 15% less than speed of boat. Then find time taken by boat to go 74 km downstream?
A boat can cover 150 km in downstream in 15 hours and 120 km in upstream in 12 hours. Find the distance travelled by the boat in still water in 5 hours.
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....
A man rows to a place 42 km away and comes back to the starting point. If the speed of the stream is 2 km/hr and the speed of the boat in still water is...
When travelling downstream, a boat takes 5.25 hours to travel 252 km. If the speed of the stream is (3/8)th of downstream speed of the boat, ...
