A boat travels faster than the stream by 28 km/h. It covers a distance of 112 km upstream and returns 132 km downstream, all within 7 hours. Calculate t...
A boat goes 200 km downstream in 50 hours, and 90 km upstream in 30 hours. The speed of the stream is
A boat running downstream covers a distance of 36 km in 6 hrs and covering the same distance upstream in 9 hrs. What is the speed of a boat in still water?
Two boats A and B start towards each other from two places, 660 km apart. Speed of the boat A and B in still water are 30 km/h and 25 km/h respectively....
A boat can cover 90 km upstream and 225 km downstream in 15 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
A boat covers a distance of 150 km while moving in a downstream in 5 hours. When the boat covers a distance of 60 km in still water in 3 hours, then Wha...
The speed of current is 26 km/hr. If the speed of the boat in still water had been 12 km/hr more than the original speed then it would take 7.5 hours to...
The time taken by the boat to cover (d+130) km distance in downstream is 1.9 hours less than the time taken by the same boat to cover (d-45) km distance...
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 ...
