Jimmy and his family are on their way to visit some family friends who live 780 miles away from them. the distances and average speeds for the first days driven are first day 4 hours at a speed of 60 miles per hour and the second day 6 hours at a speed of 65 miles per hour. if the average speed on the third day is 60 miles per hour, how many more hours will it take for them to reach their family friends' home?

If they drive an average of 60 miles per hour the last day it will take them 2.5 hours.

4 hours at 60 miles per hour = 4*60 = 240 miles

6 hours at 65 miles per hour = 6*65 = 390 miles

This is a total of 630 miles.  There are 780-630=150 miles left; if they average 60 miles per hour, that would be 150/60 = 2.5 hours.

y + 11 = (1/4)(x + 16)
