Bob walks 5 mph,then jogs 9 mph for one hour. The total distance is 6 miles.
How far did he walk.
--------------------
Walk DATA:
rate = 5 mph ; time = x hrs ; distance = 5x miles
--------
Jog DATA:
rate = 9 mph ; time = 1-x hrs ; distance = 9(1-x) miles
-----
Equation:
distance + distance = 6 miles
5x + 9(1-x) = 6
5x + 9-9x = 6
-4x = -3
x = 3/4 hr.
---
Walk distance: 5x = 5(3/4) = 15/4 = 3 3/4 miles
