(10%) Problem 10: A boat can be rowed at a speed of 6.56 km/h in still water. The boat is in a river that moves at a speed of 3.65 km/h. The river is 0.545 km wide and flows in a straight line and has straight banks. 17% Part (a) How much time, in minutes, is required to row 1.63 km downstream (with the flow) in the river?

A 17% Part (c) At what angle. in degrees, to the bank should the boat be aimed if it is to move straight across the river (perpendicular to the river ow)? A 17% Part ((1) Following up on part (c), how long, in minutes, does it take to row across the river to the other bank if the boat is aimed to move straight across the river? A 17% Part (e) Suppose the boat is directed straight across the river rather than angled to compensate for the river's ow. In this case how much time, in minutes, does it take the boat to get to the other bank? A 17% Part (1) Following up on part (e), how far downstream, in kilometers, is the boat when it reaches the other bank if it crosses the river while directed straight across the river
