The speed of a boat in still water is 40% higher than the speed of the stream. The boat takes 4 hours to travel 96 km downstream. If the boat's speed in...
A boat takes 270 minutes to travel 90 km in upstream. The same boat in the same stream takes 120 minutes to travel 50 km in downstream. Find the distanc...
Speed of a boat in still water to speed of boat in upstream is 7:4. If the boat can travel 450 km in downstream in 5 hours, then find the time taken by ...
A boat can travel 36 km downstream in 40 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 4. How much time will t...
A boat is navigating a river with a current speed of 2 km/h. It takes the boat 75 minutes longer to cover a distance of 56 km upstream than it does to c...
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 man rows to a place 48 km distant and comes back in 14 hours. He finds that he can row 4 km with the stream at the same time as 3 km against the strea...
A man can go on a motorboat with a speed of 18 km/hour in still water to a certain upstream point and return to the starting point in a river that flows...
The speed of a boat in still water is 6 km/hr more than that of the current. The time taken by the boat to cover 625 km downstream is 12.5 hours. Find t...
Boat ‘A’ can cover 120 km in still water in 10 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 4:5 and the sp...
