Micah walks on a treadmill at 4 miles per hour. He has walked 2 miles when Luke starts running at 6 miles per hour on the treadmill next to him. If their rates continue, will Luke's distance ever equal Michah's distance. Explain.
-------------
Note: Micah's time to run 2 miles at 4 mph = 1/2 hour.
------------------------
Micah DATA:
rate = 4 mph ; time = x+(1/2) hrs ; distance = 4(x+(1/2)) = 4x+2 miles
-----------------------------------------------------------------------
Luke DATA:
rate = 6 mph ; time = x hrs ; distance = 6x miles
----
Equation:
distance = distance
4x+2 = 6x
2x = 2
x = 1 hr.
----
Distances will be equal after Luke has run for one hour.
