I saw that they gave us the diameter instead of the radius. So I divided 20/2 to get 10 for the radius, because radius is half diameter. Then we used the formula 2pir to find the circumference. Then we multiplied that number by 3/8. The 3 is the number of laps and 8 is the minutes. I divided the number instead of multiplied because I needed distance traveled in a minute. Using that number I multiplied it by 20 to get 471.239 or 150Pi meters in 20 minutes.
