For my calculations, I took the average of these numbers: 192.5 feet.
The number of feet in a mile is 5,280. The number of laps in one mile is (5,280 ft /192.5 ft) = 27.4 laps.
25 laps is equal to 0.91 miles (25 laps /27.4 laps).
Therefore, the skater must travel 0.91 miles in 5 minutes.
We all know that velocity is distance divided by time.
5 minutes is equal to 0.083 hours (5 minutes / 60 minutes).
Therefore, a skater must travel 0.91 miles in 0.083 hours.
0.91 miles / 0.083 hours = 10.9 miles per hour.
∴ In order to skate 25 laps in 5 minutes, a skater must travel at an average velocity of 10.9 miles per hour.
Many girls on the team can skate over 25 laps. My personal record is 31. Looking at our team's time trial data, it looks like the maximum number anyone has done (recently) is 34. MPH equivalents for other laps below:
