Fernando's family traveled 272 miles on a road trip last weekend. they drove for four hours. what was the rate at which fernando's family traveled? write and solve a multiplication equasion.

Total distance traveled by Fernando's family = 272 miles
Time taken to travel the distance of 272 miles = 4 hours
Then we can say that
The distance traveled by Fernando's family in 4 hours = 272 miles
So
The distance traveled by
Fernando's family in 1 hour = (272/4) * 1 miles
                                             = 68 miles
From the above deduction we can easily conclude that Fernando's family traveled at a rate of 68 miles per hour. I hope to have helped you. 

x = -4.

Step-by-step explanation:

y^2-3y-40/y^2+9y+20

=  ( y - 8)(y + 5) / (y + 5)(y + 4)

= (y - 8)/(y + 4)

So the restriction is when x +4 = 0

That is when x = -4.
