Frank and Michael both leave the park at the same time, but in opposite directions. If Michael travels 4 mph faster than Frank and after 8 hours they are 176 miles apart, how fast is each traveling?
--------
Michael DATA:
rate = x+4 mph ; time = 8 hrs ; distance = r*t = 8(x+4) miles
------
Frank DATA:
rate = x mph ; time = 8 hrs ; distance = 8x miles
==========
Equation:
dist + dist = 176 miles
------
8x + 8x+32 = 176
16x = 144
x = 9 mph (Frank's rate)
------
x+4 = 13 mph (Michael's rate)
---------------------------
