A certain river is 0.5 mi wide, and flows due east at 2.7 mi/h relative to the shore. A boat attempts to cross the river straight from one shore to the other. If the boat travels due north at 1.7 mi/h relative to the river,
(a) what is the speed of the boat relative to the shore?
(b) how far downstream is the boat when it reaches the opposite shore?

URGENT A 400.0-m-wide river flows from west to east at 30.0 m/min. Your boat moves at 110 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)Where on the north shore will you land if you...
