You can put this solution on YOUR website! A bicyclist and a hiker leave the same place at the same time and travel in the same direction. The bicyclist travels three times as fast as the hiker. At the end of 3 hours they are 24 miles apart. How fast does the hiker travel?
-----------------------------
Bicyclist DATA:
rate = 3x mph ; time = 3 hrs ; distance = rt = 9x miles
----------------------------------
Walker DATA:
rate = x mph ; time = 3 hrs ; distance = rt = 3x miles
----------------------------
Equation:
9x -3x = 24 miles
6x = 24
x = 4 mph (hiker rate)
