Jill is 11 kilometers away from Joe.  Both begin to walk toward each other at the same time.  Jill walks at 2.5 kilometers per hour.  They meet in 2 hours.  How fast is Joe walking?

jill=2.5km/hr

joe=x

distance=11

time=2hrs

relative speed=11/2=5.5km/hr=joe-jill=x-2.5

x=5.5+2.5= 8km/hr

joe walks at 8km/hr
