1. Homework Statement
A boat leave a dock at noon and heads weat at a speed 25km/h. Another boat heads north at 20km/h and reaches the same dock at 1:00 pm. when were the boats closest to each other?
2. Homework Equations
when were the boats closest to each other?
3. The Attempt at a Solution
I use the pythagorean for the distance
but I'm not sure about how to sub them in?
I tried to assume that the second boat also leaves at noon, so the total distance will be 20km. But that's wrong. Please help, thanks =P[/b]
