Answer:
[tex]Rate = \frac{320\ miles}{4\ hours}[/tex]
[tex]Rate = 80\ miles/hour[/tex]
Step-by-step explanation:
Given
[tex]Distance = 320\ miles[/tex]
[tex]Time = 4\ hours[/tex]
Solving (1): Determine the rate.
Rate, in this case is:
[tex]Rate = \frac{Distance}{Time}[/tex]
[tex]Rate = \frac{320\ miles}{4\ hours}[/tex]
Solving (2): Simplify the denominator to 1
[tex]Rate = \frac{320\ miles}{4\ hours}[/tex]
Divide numerator and denominator by 4
[tex]Rate = \frac{320/4\ miles}{4/4\ hours}[/tex]
[tex]Rate = \frac{80\ miles}{1\ hour}[/tex]
[tex]Rate = 80\ miles/hour[/tex]
