The formula is:
[tex]r=\frac{d}{t}[/tex]r is the rate
d is the distance in miles
t is the time in hours
From the question:
d = 185 miles
t = 2.5 hours
r = ?
Let us substitute d and t in the formula above to find r
[tex]\begin{gathered} r=\frac{185}{2.5} \\ r=74\text{ miles/h} \end{gathered}[/tex]The rate is 74 miles/hour
