<PRE><B>Question 973654</B>
A woman can bicycle 20 miles in the same time that it takes her to jog 10 miles. If she can ride 5 mph faster than she can jog, how fast can she jog?
--------------
Jog DATA::
dist = 10 miles ; rate = x mph ; time = d/r = 10/x hrs
----
Bike DATA:
dist = 20 miles ; rate = x+5 mph ; rime = 20/(x+5) hrs
--------
Equation:
time = time
10/x = 20/(x+5)
10x + 50 = 20x
10x = 50
x = 5 mph (jogging rate)
