The complex fraction represents the unit rate in miles per hour is option (B) [tex]\frac{5}{2} /\frac{1}{6}[/tex]
Distance is a numerical measurement of how far apart objects or points are.
A unit rate means a rate for one of something
The unitary method is a technique for solving a problem by first finding the value of a single unit
Distance travelled = [tex]2\frac{1}{2} =\frac{5}{2}[/tex] miles
A sailboat travels a distance of [tex]\frac{5}{2}[/tex] miles in [tex]\frac{1}{6}[/tex] of an hour
Therefore, unit rate in miles per hour = [tex]\frac{5}{2} /\frac{1}{6}[/tex]
Hence, the complex fraction represents the unit rate in miles per hour is option (B) [tex]\frac{5}{2} /\frac{1}{6}[/tex]
