Answer by texttutoring(324) (Show Source): You can put this solution on YOUR website!
They meet in 5 hours, and Jill walks at 3 km/hr.

You need to use the formula D=VT, where D=distance, V=velocity (or speed) and T=time.

Jill:
D=VT
D=(3)(5)
D=15

So Jill travelled 15 km.

Jill and Joe started 27.5 km apart, which means that Joe must have travelled 27.5-15 = 12.5 km. We know he also walked for 5 hours.

Solve for V in the Joe equation:

V = D/T
V = 12.5 / 5
V = 2.5

So Joe is walking 2.5 km/h.
