Answer:
Therefore the unit Rate describes Wilson speed is option C.
C. 60 miles per hour.
Step-by-step explanation:
Given:
In the table
120 miles = in 2 hours
180 miles = in 3 hours
240 miles = in 4 hours
Speed:
Speed is defined as the rate of distance covered in per unit time.
It is given as
[tex]\textrm{Speed }=\dfrac{\textrm{Distance}}{Time}[/tex]
Substituting the given values we get
[tex]\textrm{Speed }=\dfrac{120}{2}=60\ miles\ per\ hour[/tex]
Also for 180 miles and 240 miles we have,
[tex]\textrm{Speed }=\dfrac{180}{3}=60\ miles\ per\ hour[/tex]
[tex]\textrm{Speed }=\dfrac{240}{4}=60\ miles\ per\ hour[/tex]
Therefore the unit Rate describes Wilson speed is option C.
C. 60 miles per hour.
