<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

You need to multiply 1 and 5 plus 2.
and for 5 2/7 it would be 5 times 7 plus 2.
So...
5 2/7= 37/7
1 2/5= 7/5
Answer:
20 degrees
explanation:
