Question 280366: I would like help on the linear equation formula for this word problem:
Marcie can walk 10 miles in the same time as Frank walks 8 miles. If Marcie walks 2 miles per hour
faster than Frank, then how fast does each person walk?
Thank you

You can put this solution on YOUR website! Marcie can walk 10 miles in the same time as Frank walks 8 miles. If Marcie walks 2 miles per hour faster than Frank, then how fast does each person walk?
----------------------------------------------
Marcie DATA:
distance = 10 mi ; time = x hrs ; rate = 10/x mph
-------------------------------------------------------
Frank DATA:
distance = 8 mi ; time = x hrs ; rate = 8/x mph
----------------------------
Equation:
Marcie rate - Frank rate = 2 mph
10/x - 8/x = 2
10 - 8 = 2x
2 = 2x
x = 1 hr
=================
Marcie rate = 10/1 = 10 mph
Frank rate = 8/1 = 8 mph
==================
Cheers,
Stan H.
