A boat is to go straight across a stream that is flowing at 5.0 km/h to east. The boatman knows that his speed with respect to water is 10 km/h. the angle `theta` at which he must head the boat, and his speed relative to the shore will be

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.

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

The speed of boat in still water is 8 km/h. The boat goes 6km & back to the starting point in 2 hours. Find the speed of the stream.

A man can row with a speed of 6 km/h in still water. What will be his speed with the stream, if the speed of stream is 2 km/h?

Water is flowing in a stream with velocity 5 km/hr in an easterly direction relative to the shore. Speed of a boat is relative to still water is 20 km/hr. If the boat enters the stream heading North, with what velocity will the boat actually travel?

The river flows at 4 km/h. A boat can go downstream thrice as fast as upstream The speed of boat in still water is
