Take the 2-minute tour ×  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.  Method 1:  Calculate the additional
5% from the total mile time (Laps 1 & 2 together) for a constant
speed projection.  Method 2:  Calculate the additional 5% from
the Lap 2 total time to take into account the deceleration over
