Question

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?

Answer 1

Unit rate in miles per hour = 4.5

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

`L=(3)/(4)miles`

Time taken to cover this loop on Monday

`t=(1)/(6)hours`

Unit rate in miles per hour,

`v=(l)/(t)=((3)/(4))/((1)/(6))=(18)/(4)=4.5miles/hour`

Unit rate in miles per hour = 4.5
