Act One
 Teacher noteWhy aren't they the same ratio? There's some rounding that happened (since the billboard can't display the tenths place). In other words, the 4 minutes should really be interpreted as [3.5, 4.5), etc.
Act Two
 Teacher noteI'd set up 3.5 (less than or equat to) t (less than) 4.5 to begin doing this algebraically, then tie in d = rt. Allows you to establish some intervals for possible speed limits. In the end, only one reasonable solution (55 mph) remains.
Act Three
 Teacher noteI'll add a picture of the speed limit sign shortly.
