Homework Statement
A boat takes 4.0 hr to travel 25 km down a river, then 5.0 hr to return.
A. How fast is the river flowing?
B. What is the velocity of the boat relative to the water flow?
Homework Equations
VAC=VAB+VBC
The Attempt at a Solution
For some reason I have trouble thinking in terms of the equation... I keep thinking that I can simply divide the time by distance traveled which yields a velocity of 6.25 km/hr for one direction and 5.0 km/hr for the return. Any help is appreciated.
Thanks.
EDIT: This should probably be in Introductory Physics, sorry. Any help on this section is still appreciated. Thanks =)
