Everett is riding his dirt bike on a circular motocross track. The track has a radius of 0.6 miles. How many times around the track does Everett need to ride to cover a distance of at least 30 miles?

8 times
Explanation: since the radius is 0.6 the diameter is 1.2 and you can multiply that by pi to get the circumference, and then 30 divided by the circumference rounded to the next while number is your answer, and that comes out to 8
