A river flows due East at 0.979 m/s. A boat crosses the river from the South shore to the North shore by maintaining a constant ve-
locity of 12.8 m/s due North relative to the
water. The river is 306 m wide.
What is the velocity of the boat relative to
shore? Answer in units of m/s.

    I visualize a right triangle:

    velocity:sqrt(12.8^2+.979^2)

    now for velocity, you need an angle;

    theta off of the N direction= arctan .979/12.8
