You can put this solution on YOUR website! 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
