In a harbour, wind is blowing at the speed of `72km//h` and the flag on the mast of a boat anchored in the harbour flutters along the N-E direction. If the boat starst moving at a speed of `51km//h` to the north. What is the direction of the flag on the mass of the boat?

In a harbour, wind is blowing at the speed of 72 km //h and the flag on the mast of a boat anchored in the harbiyr flutters along the N-E direction. If the boat starts moving at a speed of 51 km// h to the North, what is the direction of flag on the mast of the bat ?

A political party has to start its procession in an area where wind is blowing at a speed of 30 sqrt(2) km h^-1 and party flags on the cars are fluttering along north - east direction. If the procession starts with a speed of 40 km h^-1 towards north, find the direction of flags on the cars.

A boat travels upstream at the speed of 20 km/h and downstream at the speed of 30 km/h. What is the speed of the boat.

At a harbour, a boat is standing and wind is blowing at a speed of sqrt(2)m//sec. due to which , the flag on the boat flutters along north - east. Now the boat enters in to river, which is flowing with a velocity of 2m//sec . Due north. The boat starts with zero velocity relative to the river and its constant acceleration relative to the river is 0.2m//sec^(2) due east. In which direction will the flag flutter at 10 seconds ?

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.

A child in danger of drowning in a river is being carried downstream by a current that flows uniformly at a speed of 2.5 km//h. The child is 0.6 km from shore and 0.8 km upstream of a boat landing when a rescue boat sets out. If the boat proceeds at its maximum speed of 20 km//h with respect to the water, what angle does the boat velocity v make with the shore? How long will it take boat to reach the child?

A boat covers a distance of 14 km in 4 hours along the flow. What is the speed of the boat in still water, if the speed of the flow of water is 2 km/h?

A man is on ship which is moving in east direction with speed 60km//hr. Waves of ocean is taking ship towards west with speed 20km//hr . Man start running on ship with flag in his hand in north direction with speed 30km//hr and wind is blowing with 50km//hr,37^(@) towards south of west then find the direction of flutter the flag as seen by man on ground.

The speed of a boat itself is 30 km/h and the rate of flow of the stream is 5 km/h. Moving against the stream the boat went 200 m. What distance will the boat cover during the same time going in the direction of the stream?
