Question

Last week, Sia ran 1(1)/(4) miles each day for 5 days and then took 2 days off. Did she run at least 6 miles last week? First, model the problem. Describe your model.

Answer 1

Sia ran 1.25 miles per day for 5 days, totaling 6.25 miles for the week, which is more than 6 miles, answering the question affirmatively.

Step-by-step explanation:

To model the problem of whether Sia ran at least 6 miles last week, we need to multiply the number of miles she ran each day by the number of days she ran. Sia ran 1(1/4) miles each day for 5 days. This is equivalent to 1.25 miles each day. To find the total number of miles, we multiply 1.25 miles by 5 days:

1.25 miles/day × 5 days = 6.25 miles

This indicates that Sia ran a total of 6.25 miles last week, which is more than 6 miles. Therefore, the answer to the question is yes, Sia did run at least 6 miles last week.
