Twp boats are moving along perpendicular paths on a still take at right. One boat moves with a speed of `3 ms^(-1)` and the other boat moves with a speed of `4 ms^(-1)` in the directions such that they collide after some time. At t=0, the boats are 300 m apart. Two boats will collide after time ______.

Two boats A and B are moving along perpendicular paths in a still lake at night. Boat A move with a speed of 3 m//s and boat B moves with a speed of 4 m//s in the direction such that they collide after sometime. At t=0 , the boats are 300 m apart. The ratio of distance of distance travelled by boat A to the distance travelled by boat B at the instant of collision is :-

A person rows a boat in a water with a speed of 4 ms^(-1) . Water in the river is flowing with a speed of 2 ms^(-1) . If the person rows the boat perpendiculat to thedirection of flow, find resultant velcity of the boat and time taken by boat to cross the river if widthe of the river is 400 m .

A motor boat is moving at a steady speed of 36.km*h^(-1) . If the water resistance to the motion of boat is 4000N, calculate the power of the engine.

Two boats A and B moved away from a buoy anchored in the middle of a river along the mutually perpendicular straight lines. A moved along the river and B at fight angle to it Having moves off equal distances from the boy, the boats returned. Find the ratio of the times of motion of the boats, if the velocity of each boat with respect to still water in eta =1.2 times greater than the velocity of water current.
