<PRE><B>Question 820558</B>
Me.sheen rode a distance of 12miles out into the country on a bicycle and returned on foot. His rate of the bicycle was 4 times his rate on foot. He spent 5 hours on the entire trip. Find his rate of walking.
---------------
Out DATA:
distance = 12 miles ; rate = x mph ; time = d/r = 12/x hrs
----------
Back DATA:
distance = 12 miles ; rate = 4x mph ; time = d/r = 12/4x hrs
----------
Equation:
time + time = 5 hours
12/x + 12/4x = 5
4*12 + 12 = 20x
-------
20x = 60
x = 3 mph (walking rate)
