Question 206075
The formula R= - 0.0065t + 4.3222 can be used to predict the world record, in minutes, for the 1-mi run t years after 1900. Determine in terms of an inequality) those years for which the world record will be less than 3.7 minutes. 
--------------------------------------------
-0.0065t + 4.3222 < 3.7
-0.0065t < - 0.6222
t > 95.72
-------------------
Year: 1900+95.72 puts you in the year 1996
Ans: 1996 and beyond
