Question

I understand that x=vt is the equation we use for this problem ,but I don't why the answer would be x=(1.1m/s )(234s).Why do we use 1.1 m/s as the velocity instead of 3.4 m/s which is the magnitude of the velocity relative to earth?

A river flows due south with a speed of 1.1 m/s. A
man steers a motorboat across the river; his
Part D
velocity relative to the water is 3.2 m/s due east.
The river is 750 m wide.
How far south of his starting point will he reach the opposite
bank?
