bahrom7893 · Answer

uhmm right let's organize this:
let d be the distance traveled.

bahrom7893 · Answer

Let V be the speed of the boat, then:
V+4 = d/2
V-4 = d/3

bahrom7893 · Answer

now solve for V

anonymous · Answer

okay for the first one I got v=-4+2d? I am anywhere close?

bahrom7893 · Answer

no it's d/2 not 2d. V = -4+d/2. Now plug that into the 2nd equation

anonymous · Answer

okay I'm stuck I got d/2-8=d/3 I don't know where to go from there
