A boat crosses a river of width 113 m in which

the current has a uniform speed of 0.933 m/s.

The pilot maintains a bearing (i.e., the direction in which the boat points) perpendicular

to the river and a throttle setting to give a

constant speed of 2.58 m/s relative to the water.

What is the magnitude of the speed of the

boat relative to a stationary shore observer?

How far downstream from the initial position

is the boat when it reaches the opposite shore?
