Answer: \(2\dfrac{2}{3}\text{ miles per hour}\)
Step-by-step explanation:
Jeremy can row \(\dfrac{2}{3}\) of a mile in \(\dfrac{1}{4}\) of an hour.
The formula for unit rate (in miles per hour) is given by :-
\(\text{Unit rate}=\dfrac{\text{Distance in miles}}{\text{Time}}\\\\\Rightarrow\ \text{Unit rate}=\dfrac{\dfrac{2}{3}}{\dfrac{1}{4}}\)
i.e. \(\text{Unit rate}=\dfrac{2}{3}\times\dfrac{4}{1}\\\\=\dfrac{8}{3}=2\dfrac{2}{3}\text{ miles per hour}\)
Hence, the unit rate =\(2\dfrac{2}{3}\text{ miles per hour}\)
