A captain can navigate a ship at a speed of 5 km/hr in calm waters. With a current moving at a speed of 3 km/hr, he takes 12 hours longer to travel 'd' ...
A boat can cover 110 km in upstream in 11 hours and 140 km in downstream in 7 hours. Find the speed of the stream.
A boat’s speed against the stream is 66.67% less than its speed in still water. If it covers 180 km downstream in 4 hours, find the time (in minutes) ...
A boat traveled 100 km downstream. The boat's speed in still water is 30 km/h, and the stream's speed is 10 km/h. Calculate the time required for the bo...
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 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) ...
A boy can swim a certain distance downstream in 6 hours and return in 7 hours. If the rate of stream is 3 kmph then what is the speed of boy in still wa...
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...
