Homework Statement
A boat takes 2.0 hr to travel 31 km down a river, then 6.0 hr to return. How fast is the river flowing?
Homework Equations
r=d/t
The Attempt at a Solution
first started out by finding the rate the boat traveled in each trip.
31/2=15.5 km/hr
31/6=5.2 km/hr
Now this is where I am not sure if I am solving this correctly. I then find the difference between the two rates and the time taken to travel both ways.
10.3 (difference of 15.5-5.2)/4(difference of 6-2)=2.6 km/hr
Is this the correct way of solving this problem? Thanks!
