A river is flowing with velocity 5km//hr as shown in the figure. A boat start from A and reaches the other bank by covering shortest possible distance. Velocity of boat in still water is 3km//hr . The distance boat covers is.

A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is :

A boat goes 12 km upstream and 40 km downstream in 8 hours. It can go 16 km upstream and 32 km downstream in the same time. Find the speed of the boat in still water and the speed of the stream

A boat takes 4 hrs to travel certain distance in a river in down stream and it takes 6 hrs to travel the same distance in upstream. Then the time taken by the boat to travel the same distance in still water is

We know that when a boat travels in water, its net velocity w.r.t. ground is the vector sum of two velocities. First is the velocity of boat itself in river and other is the velocity of water w.r.t. ground. Mathematically: vecv_(boat) = vecv_(boat,water) + vecv_(water) . Now given that velocity of water w.r.t. ground in a river is u. Width of the river is d. A boat starting from rest aims perpendicular to the river with an acceleration of a = 5t, where t is time. The boat starts from point (1,0) of the coordinate system as shown in figure. Assume SI units. Find time taken by him to across the river.

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.

A man crosses the river perpendicular to river in time t seconds and travels an equal distance down the stream in T seconds. The ratio of man's speed in still water to the river water will be:
