The speed of the stream is 15 km/h. Boat ‘A’ covers 100 km distance against the stream in 4 hours and boat ‘B’ covers 90 km distance against the...
A boat takes 20 hours to travel 260 km downstream. The speed of the boat in still water is 125% greater than the speed of the stream. If the boat comple...
A boat travels downstream at a speed that is (13/12) times its speed in still water. If the boat takes 3 hours to cover 132 km going upstream, how long ...
A person rows 300 km against the current in 5 hours and travels 540 km along the current in 6 hours. How much time will he take to row 660 km in still w...
The water in a river flow at the rate of 4 km per hour if the width and depth of the river are 8 M and 4 m respectively then how much water will enter ...
A boat goes 5 km an hour in still water, but takes twice as much time in going the same distance against the current. The speed of the current (in km/ho...
The speed of a boat in still water is 12 times the speed of the stream. If the difference between the upstream and downstream speed of the boats is 20 k...
A boat can cover 170 km in downstream in 2 hours and 145 km in upstream in 5 hours. Find the speed of boat in still water.
A boat moves 25km upstream and 39km downstream in 8 hours. It travels 35km upstream and 52km downstream in 11 hours. What is the speed of the stream if ...
The speed of the boat in still water is 10 km/h and the speed of the stream is 6 km/h. A boat goes 48 km downstream with its usual speed but at t...
