Question 738838: Your boat goes 20 MPH full throttle. You are going downstream at full throttle, 20 MPH. The river is flowing at 10 MPH. The river is straight and there is a straight road beside the river. How fast will a car have to travel to keep up with the boat? 20 MPH or 30 MPH?
Thanks Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! The speed of the current gets added to the
speed of the boat, so mi/hr
A car beside the boat would also have to
travel at mi/hr
