Question

maintaining a constant velocity of 10.7 m/s due North relative to the water. The river is 459 m wide.

i already figured that the velocity of the boat is 10.76055761 m/s

but how far downstream has the boat moved by the time is reaches the North shore? answer in meters

Answer 1

The time it takes the boat to cross the river is
459/10.7
42.9 seconds

In that time the river carries the boat downstream (East) according to
1.41*42.9 m
60.5 m
