Homework Help: Algebra 1

Posted by Nikki on Sunday, November 21, 2010 at 5:45pm.

The world record for the mile was 4:10 and 3:49 in 1975. Assuming that the record improves in a linear fashion (which it has so far) write an equation to predict the mile world record (in seconds) for a given year (y=record in seconds, x=year)

What should the world record be this year?

What should the world record be in 2001?

The world record was broken in 1993 by Noredine Morceli. What is the current world record in the mile? How does this compare to your prediction above?
