Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is 3/4 of a mile long. On Monday, Selma ran the loop in 1/6 of an hour. What is Selma's unit rate in miles per hour for Monday's run?

Respuesta :

Answer:

Unit rate in miles per hour = 4.5

Step-by-step explanation:

Unit rate in miles per hour is the ratio of total distance covered in miles to total time taken in hour to cover that distance.

Total distance covered in miles = Length of loop

            [tex]L=\frac{3}{4}miles[/tex]

Time taken to cover this loop on Monday

            [tex]t=\frac{1}{6}hours[/tex]

Unit rate in miles per hour,

            [tex]v=\frac{l}{t}=\frac{\frac{3}{4}}{\frac{1}{6}}=\frac{18}{4}=4.5miles/hour[/tex]

Unit rate in miles per hour = 4.5
