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.
A boat can cover 60 km in still water and 75 km in downstream in 4 hours and 3 hours respectively. Find the time taken by the boat to cover 60 km upstre...
A man rows 40 km upstream and 60 km downstream in 8 hours. If the ratio of his upstream speed to downstream speed is 2:3, then find the time required to...
A boat takes 7 hours to cover 245 km upstream and 9 hours to cover 477 km downstream. Find the time taken by the boat to cover 410 km upstream and 495 k...
The speed of a boat downstream is 20% more than the speed of the boat in still water. If the boat can travel a distance of 288 km upstream in 18 hours, ...
The speed of the stream is 15 km/h. Boat ‘A’ covers 140 km distance against the stream in 4 hours and boat ‘B’ covers 105 km distance against th...
A boat travels from point 'Y' to point 'Z' downstream and then returns to point 'X', which is located midway between 'Z' and 'Y'. The entire trip takes ...
A man rows to a place 221 km away and comes back to the starting point. If the speed of the stream is 2 km/hr and the speed of the boat in still water i...
Ratio of speed of boat in downstream and speed of stream is 7:4, if speed of current is 8 km/hr, then find distance travelled (in km) upstream in 7 hours.
Time taken by boatman to travel a distance of (d + 60) km downstream and (d + 120) upstream is 10 hours and 20 hours respectively, and the downstream sp...
