-------------
To the meeting DATA:
Time=9 hrs ; distance = x miles ; Rate = x/9 mph
-----------------
From the meeting DATA:
Time = 8 hrs; distance = x miles ; Rate = x/8 mph
-----------------
EQUATION:
x/8-x/9 = 2 hrs
x/72 = 2
x = 144 miles
----------------
Rate to the meeting: x/9=144/9 = 16 mph
---------------
Rate from the meeting: x/8= 144/8 = 18 mph
