Acircular jogging track forms the edge of a circular lake that has a diameter of 2 miles. johanna walked once around the track at the average speed of 3 miles per hour. if t represents the number of hours it took johanna to walk completely around the lake, which of the following is a correct statement? a. 0.5< t < 0.75b. 1.75< t < 2.0c. 2.0 < t < 2.5d. 2.5 < t < 3.0e. 3 < t < 3.5

Option C is the answer.

Step-by-step explanation:

Given diameter is = 2 miles

So, radius will be = 1  mile

Let t represents the number of hours it took Johanna to walk completely around the lake.

Now, the circumference is given as:

So, circumference = = 6.28 miles

Johanna's speed = 3 miles/ hour

We know the formula

t =

t = 2.09 hours

This is greater than 2, but less than 2.5, therefore, 2.0 < t < 2.5 is the answer.
