My friends and I are having an argument.
I bet my friend that he could not run a mile in under 12:00 minutes, which he did, but it lead to a question. The mile he ran was on a field the size of half of a mile. He ran two laps. During his run, my friend accidentally skipped 5% of each lap. Since he had not run a mile (or anything) in over 5 years, he started out fast and decelerated over the course of the mile. In total, he finished 95% of the mile in 11:00.
My question is, if we were to project the total running time to 100% based on the information below, which of the two methods below (ONLY THE METHODS LISTED BELOW) would give the most accurate estimation?
- 95% of a mile completed in 11:00.
- Lap 1 completed in 3:40.
- Lap 2 completed in 7:20.
Calculate the additional 5% from the total mile time (Laps 1 & 2 together) for a constant speed projection.
Calculate the additional 5% from the Lap 2 total time to take into account the deceleration over time.
