<span>1. </span><span>Fiona drives 60 miles per hour on
the Highway
And drives 30 miles per hour on the City.
She got a total of 312 hours in the highway and 112 hours in the city
Find the average speed of Fiona:
Formula of Speed
=> S = d / t
Let H be the distance in Highways
and Let C be the distance in City
=> H = 60 x 312
=> H = 18 720
=> C = 30 x 112
=> C = 3360
=> Total distance = 18 720 + 3 360
=> 22 080 miles
Let’s find the total time
=> H + C
=> 312 + 112
=> 424 hours
Speed = 22 080 / 424
S = 52.1 miles per hour

3(x + 3y) - 5(x-7)
Use the distributive prop. to simplify
3x + 9y - 5x - 35
Use The assoc. prop to move them around.
3x - 5x + 9y - 35
combine like terms
-2x + 9y - 35
