A riverboat travels with a velocity of 4.60 m/s from one shore to another. The velocity of the river is 2.30 m/s. If the width of the river is 72.0 m, how far does the boat travel downstream to reach the other shore?

you can make this hard (or more general) by setting up distance/speed calculations, and all that, but just notice that
the river's speed is 1/2 that of the boat.
So, the boat goes downstream 1/2 as far as it goes across.
