Jeremey can row 3/8 of a mile in 1/4 of an hour. To find the unit rate, we need to find how many miles he can row in 1 hour. To find it, we can use the next proportion:
[tex]\frac{\frac{3}{8}\text{ miles}}{x\text{ miles}}=\frac{\frac{1}{4}\text{ hour}}{1\text{ hour}}[/tex]Solving for x:
[tex]\begin{gathered} \frac{3}{8}\cdot1=\frac{1}{4}\cdot x \\ \frac{3}{8}\cdot4=x \\ \frac{3}{2}\text{ miles = x} \end{gathered}[/tex]The unit rate is 3/2 miles per hour
