Homework Help: Algebra

Posted by Claudizzle on Wednesday, October 7, 2009 at 5:23pm.

Janet left her college campus 2 h after Juanita. They traveled in opposite directions. Janet drove at 50 mi/h and Juanita drove at 62 mi/h. How many hours after Juanita left were the two girls 380 miles apart?

My work:

380 = 50(t-2)+62t
380 = (50t-100)+62t
380 = 112t-100
480 = 112t
/112= /112
4.285714286 = t

-Did I get "t" right?
-And if I didn't what did I do wrong?
