Answer: [tex]2\frac{4}{5}\text{ miles per hour}[/tex]
Step-by-step explanation:
Given :- Julio walks [tex]3\frac{1}{2}[/tex] miles in [tex]1\frac{1}{4}[/tex] hours.
first convert distance and time in improper fraction.
Distance= [tex]3\frac{1}{2}=\frac{7}{2}[/tex] miles
Time taken= [tex]1\frac{1}{4}=\frac{5}{4}[/tex] hours
Now, the unit rates=
[tex]\frac{\text{Distance}}{\text{Time}}\\=\frac{\frac{7}{2}}{\frac{5}{4}}=\frac{7}{2}\times\frac{4}{5}\\=\frac{14}{5}\\=2\frac{4}{5}\text{ miles per hour}[/tex]
⇒ Julio walks [tex]2\frac{4}{5}\text{ miles}[/tex] in 1 hour.
