Step-by-step explanation:
First, we are going to use the formula of the circumference of a circle:

where

is the circumference of the circle.

is the radius of the circle.
We know for our problem that the diameter of Ubehebe Crater is 1 mile. Since the radius of a circle is half its diameter, the radius of our crater will be:

. Lets replace that value in our formula:



miles
Next, we are going to use the distance speed time formula:

where

is time

is distance

is speed
We know for our problem that Latisha walks around its rim at a rate of 2 miles per hour, so her speed is 2 mph; therefore,

. We also know for our previous calculation that the circumference of the crater is 3.14 miles, so

. Lets replace those values in our formula to find

:



hours
We can conclude that it will take Latisha 1.6 hours <span>
to walk all the way around the crater.</span>
