Hello!!!!
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 miles6 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.
Hope this helps!

Given expression: (A+b)^3.
We can expand it into three factors as (A+b)(A+b)(A+b).
First we would foil (A+b)(A+b) = 
Combining like terms, we get
= 
Now, we would multiply (A^2 +2Ab + b^2) and (A+b).
=
Combining like terms, we get

Therefore,
