<font color=black size=3>
Question: Mary left Atlanta with a speed of 45mph. Fred also left at the same time in the opposite direction at a speed of 60mph. Find how many hours Fred must travel before they are 318 miles apart


------------------------


x = number of hours


Mary:
distance = rate*time
d = 45x


Fred
d = 60x


Distance between Mary and Fred = 45x+60x = 105x


We want that distance to be 318 miles
105x = 318
x = 318/105
x = <font color=red>3.02857 hours approximately</font>
