A boat crosses a river of width 113 m in which

Question

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?

Answer 1

speedboat^2=.933^2+2.58^2

time across: 113m/2.58m/s

downstream distance along river: .933*timeacross

Answer 2

Thank you! :)
