Answer:
C
Step-by-step explanation:
The formula given is:
[tex]d=26t+32.5[/tex]
Where
d is the distance between two cars
and
t is the time it takes
We want the time it takes (so we need t) for the cars to be 117 miles apart (this is the distance). Thus, it means:
d = 117
t = ???
We plug in 117 into d and solve the equation for t. Shown below:
[tex]d=26t+32.5\\117=26t+32.5\\117-32.5=26t\\84.5=26t\\t=\frac{84.5}{26}\\t=3.25[/tex]
So, it takes 3.25 hours
Correct answer is C
