------
Walk DATA:
rate = 2 mph ; time = t hrs ; distance = 2t miles
------------
Jog DATA:
rate = 5 mph ; time = (t-(1/15)) hrs ; distance = 5(t-(1/15)) miles
------------
Equation::
dist = distance
2t = 5t - 3 ********* should be 5t - 1/3
3t = 3
t = 1 hr
-----
Ans:: dist = 2t = 2 miles

------------
d = r*t
d = 2t = 5(t- 1/15)
2t = 5t - 1/3
t = 1/9 hour
-----
d = 2/9 miles
==============
Check:
2*1/9 = 2/9 miles
(1/9 - 1/15)*5 = 5/9 - 1/3 = 2/9 miles
