Advanced PhysicsQ&A LibraryReview | Constants 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?

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?
