A river flows due south with a speed of 2.00 m/s. A man steers a motorboat across the river; his velocity relative to the water is 4.20 m/s due east. The river is 800 m wide.

What is the magnitude of his velocity relative to the earth?
got it....4.65 m/s

What is the direction of his velocity relative to the earth?
got it....25.5 degrees south of east

How much time is required for the man to cross the river?
don't know...

How far south of his starting point will he reach the opposite bank?
don't know....

don't know...
What is the distance across (given) and his speed due east (given)?

How far south of his starting point will he reach the opposite bank?
don't know....

You know the time it takes to get across (just done), and his speed downstream (2.00m/s).

North of east degrees is 28...
