In July 1985 Steve Cram from Great Britain set a world record of 3 min. 29.67 sec. for the 1500 meter race and a world record of 3 min 46.31 sec for the one mile race. Suppose you know only that these two events occurred 11 days apart and that the 1500 meter record was set on July 16th. Use an absolute value equation to find the possible dates for the one mile record run.

It's like my brain shut down when it came to math when I was 12. It was always a struggle before then, and nearly impossible afterwards. I just barely got by with the help of a lot of tutors. Anyone else mathematically retarded?
