Another Two Object Moving Toward Each Other Motion Problem, but Different Form It's sort of like Motion Problem: Two Objects Moving Towards Each Other but in a different form, so I'm sort of confused. It seems easier but I also don't know how to do it. Joe and JoAnn walk toward each other from two locations 36 miles apart. If Joe departed 2 hours earlier, they would meet 2.5 hours after JoAnn departed. If JoAnn departed 2 hours earlier they would meet 3 hours after Joe departed. Find the respective speed which each walks.

$v_{Joe} (2.5+2)+v_{JoAnn} 2.5=36$

$v_{Joe} (3)+v_{JoAnn} (2+3)=36$

So we have two equations:

$v_{Joe} 4.5+v_{JoAnn} 2.5=36$

$v_{Joe} 3+v_{JoAnn} 5=36$

Now I don't think there is a problem to solve it. Try it yourself.
