A river flows due east at 1.20 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 15.0 m/s due north relative to the water.
(a) What is the velocity of the boat relative to shore?
° (north of east)
(b) If the river is 220 m wide, how far downstream has the boat moved by the time it reaches the north shore?
I can't answer~~who can help me?Thanks a lots~~~
