Plz answer :) will be marked BRAINLIEST!

Answer:
65 mph
Step-by-step explanation:
To find the unit rate (miles per hour), we can use the equation
[tex]r=\frac{d}{t}[/tex]
Where
r=rate (miles per hour)
d=distance (in miles)
t=time (in hours)
Using the given information, we can plug in
[tex]d=97\frac{1}{2}[/tex]
[tex]t=\frac{3}{2}[/tex]
So, our equation is
[tex]r=\frac{97.5}{1.5}[/tex]
When we divide 97.5 and 1.5, we get
[tex]65[/tex]
So,
[tex]r=65[/tex]
In conclusion, the rate (miles per hour) is 65 mph.
