The world record for the mile was 4 minutes and 10 seconds in 1923 and 3 minutes and 49 seconds in 1975.

a) Assuming that the record improves in a linear fashion, write an equation to predict the mile world record (in seconds) for a given year.

b) From your equation, what should the world record have been in 1999? How does it compare to the actual world’s record of 3 minutes and 43.13 seconds.
