Answer: [tex]\bold{(A)\ \dfrac{\text{51 miles}}{\text{1 hour}}}[/tex]
Step-by-step explanation:
Consider the formula "distance (d) = rate (r) x time(t)" and solve for r.
d = r · t
÷ t ÷ t
[tex]\dfrac{d}{t}=r[/tex]
Now plug in the given d and t values from the table to solve for r:
[tex]r=\dfrac{\text{204 miles}}{\text{4 hours}}[/tex]
[tex]=\dfrac{\text{51 miles}}{\text{1 hour}}[/tex] simplified the fraction
You can check this by plugging in the other 3 values from the table:
[tex]r=\dfrac{\text{306 miles}}{\text{6 hours}}[/tex]
[tex]=\dfrac{\text{51 miles}}{\text{1 hour}}[/tex]
[tex]r=\dfrac{\text{408 miles}}{\text{8 hours}}[/tex]
[tex]=\dfrac{\text{51 miles}}{\text{1 hour}}[/tex]
[tex]r=\dfrac{\text{510 miles}}{\text{10 hours}}[/tex]
[tex]=\dfrac{\text{51 miles}}{\text{1 hour}}[/tex]
