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.
