<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

Answer:
160
Step-by-step explanation:
Answer:
0.0112 liters to the nearest ten thousandth.
Step-by-step explanation:
Density = mass / volume
So volume = mass / density.
Mass = 21753 mg = 21753 / 1000 = 21.753 g.
Density = 1.935 g/mL = 1.935 * 1000 = 1,935 g/L.
Volume in liters = 21.753 / 1,935
= 0.0112 liters to the nearest ten thousandth.
