Phil and Inez start from the same place at the same time and walk in opposite directions on Tremont Street. Inez walks twice as fast as Phil. After 30 minutes they are 24 blocks apart. How far does Phil walk?
-------------
Phil DATA:
distance = x blocks ; time =30 minutes ; rate = d/t =x/30 blocks/minute
---------------
Inez DATA:
distance = 24-x blocks ; time=30 minutes ; rate = d/t = (24-x)/30 blocks/min
---------
EQUATION:
Inez rate = 2(Phil rate)
(24-x)/30 = 2(x/30)
24-x=2x
24=3x
x=8 blocks (Distance Phil walks)
