3. A speedboat is directed towards the East traveling at a speed of Vb = 15
m/s in a river. A constant river current of magnitude Vr = 2.5 m/s flows in
the northerly direction.
a) How far would the canoe have traveled during 12 seconds, at the constant
speed, if there were no current?
b) As a result of the current, what is the magnitude and direction of the
speedboat?
