Whats MapQuest's and Google Maps estimated drive time based on?
So if I were to go from Chicago to New York and it says 13 hours, 30 minutes do they base it off of the exact speed limit areas? Ex: If it's 65 Mph they base the estimated time to get there off of the speed limit or the average person driving from Chicago to New York?
The reason I ask is because my family is going to Florida and the drive is about 21 hours and 45 minutes. Most people drive about 5 Mph over the speed limit and some 10 Mph over. Is the estimated time based off of the speed limits? Thanks!

It's complicated. The actual method is a trade secret. Goggle uses real-time traffic data from various sources as well as historical data to extrapolate drive times. CHECK OUT THE BIG BRAINS AT GOOGLE!

The use the standard T= D/R formula
The reason that their times are undoable is that they use the posted speed limit as their Rate and nobody can do the posted speed limit as their average mph
If you use 50 mph as your R then you'll wind up with a more realistic T
