First, we are going to use the formula of the circumference of a circle: C=2 \pi r
where 
C is the circumference of the circle.
r 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: r= \frac{1}{2} =0.5. Lets replace that value in our formula:
C=2 \pi r
C=2*3.14*0.5
C=3.14 miles

Next, we are going to use the distance speed time formula: t= \frac{d}{s}
where
t is time
d is distance
s 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, s=2. We also know for our previous calculation that the circumference of the crater is 3.14 miles, so d=3.14. Lets replace those values in our formula to find t:
t= \frac{d}{s}
t= \frac{3.14}{2}
t=1.6 hours

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