Speed of a boat in still water is 12 kmph and speed of stream is 6 kmph. A man rows to a place at a distance of 72 km and come back to starting point. T...
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 90 km downstream.
Speed of boat is 25 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream?
A boat travels the same distance 'd' km in both upstream and downstream directions, taking a total of 15 hours for the round trip. If the downstream spe...
The ratio of speed of boat in upstream and in Stillwater is 1: 3 respectively. The boat takes a total of 10 hours to travel 300 kilometer in downstream ...
A boat goes 56 km in upstream in 4 hours and takes 3 hours to complete a distance of 18 km in downstream. Find the speed of boat in still water.
Speed of current is 25% of speed of boat in still water, if boat travelled 45 km downstream and returned back in total 12 hr. then find speed of boat i...
The speed of boat downstream and upstream is 26 km/hr and 22 km/hr respectively. Time taken to travel a distance of (p + 45) km downstream and (q + 30) ...
