The force required to tow boat at a constant velocity is proportional to the velocity. If it takes 7460 W to two a certain boat at a speed of 4 kmph, how much horse power (1 H.P = 746 watts) will be required to tow it at a speed of 12 kmph ? [Hint : Force prop velocity P = force xx velocity]

The force required to row a boat at constant velocity is proportional to the speed. If a speed of 4 kmh^(-1) requires 7.5 kW, how much power does a speed of 12 kmh^(-1) require?

When the speed of a boat in still water is 4 km/h and the rate of stream is 2 km/h, find upstream speed of the boat

If the speed of a boat in still water is 8 km/h and the rate of stream is 4 km/h, then find upstream speed of the boat.

The speed of a boat in still water is 12 km/h. If the boat covers a distance of 38 km upstream in 4 hours, then the speed of the stream (in km/h) is:

Downstream speed of boat is 50 km/h and upstream speed of boat is 30 km/h. Find the speed of boat in still water and speed of stream?
