A 400.0-m-wide river flows from west to east at 30.0 m/min. Your boat moves at 100.0 m/min relative to the water no matter which direction you point it. To cross this river, you start from a dock at point A on the south bank. There is a boat landing directly opposite at point B on the north bank, and also one at point C, 75.0 m downstream from B.

**A) To reach point C at what bearing (angle north of west) must you aim your boat? **
For this I got 83.5 deg N of W

**B) Refer to part A. How long (t) will it take to cross the river? **
For this I got 4.02 min

This is where I got stuck because I'm not sure how to do the last two parts...

**C) Refer to part A. What distance (d, as measured by an observer on the ground) do you travel in m?
**

D) Refer to part A. What is the speed of your boat as measured by an observer standing on the river bank (=|VbG|) in m/min?## Answer this Question
