Asked by Eduardo
a boat crosses a 2 km wide river by starting out at the south shore and heading directly for the north shore if the river flows at 0.8 m/s and the boat can go at 1.4 m/s in still water, where on the opposite shore will the boat land?

X = 0.8 m/s.
Y = 1.4 m/s.
tanA = Y/X = 1.4/0.8 = 1.75
A = 60.3o.
tan60.3 = Y/X = 2km/X.
X = 2km/tan60.3 = 1.14 km East of North.
Y = 1.4 m/s.
tanA = Y/X = 1.4/0.8 = 1.75
A = 60.3o.
tan60.3 = Y/X = 2km/X.
X = 2km/tan60.3 = 1.14 km East of North.
