Jessica left the city traveling at fifty seven mph, while, at the same time, Benny left the city going the opposite direction at q speed of seventy six mph.
 Find the time Jessica traveled before the two were one hundred sixty Nine miles apart.
:
Let t = the travel time of both
Write distance a equation: dist = speed * time
57t + 76t = 169
133t = 169
t = 169/133
t = 1.27 hrs, or 1 + .27(60) = 1 hr 16 min
