Guessing how many miles other people can do is tricky, because people have differing riding styles, habits, strength, etc. Here's my best advice, assuming you are on the trail more for touring more than racing.
Unless you are carrying a lot of weight on your bikes, you should easily be able to 50-60 miles per day and still have plenty of time to dawdle around, have a nice lunch, etc. If you like to ride fast and don't spend a lot of time in the towns, most people should be able to do 70-80 miles without difficulty. If you like to ride at a quick pace and push your limits a little, 100 miles is very doable, but in my opinion if you are going to ride that far in a day you are not going to have time for any fun along the way.
We usually estimate 10 miles per hour (not counting long breaks for lunch and dinner) when planning our day on the bike. For example, if we want cover 80 miles in a day and we are going have lunch at noon in a town that is 40 miles away, we need to be pedalling by 8 a.m. to get to the lunch town by noon. If we take two hours for lunch, we will pedal from 2-6pm to reach the overnight town.
That has always worked well for us. We can pedal faster than 10mph, but that planning system allows for us to ride at a comfortable pace and still take a break here and there to stop and see the sights. When we rode the Katy, we aimed for approx 60 mile days and that worked pretty well for us.
As for the hills, the ride is virtually flat from St. Charles to Boonville, then you will encounter long easy grades from Boonville to Sedalia. If you are riding both directions, it is best to ride the way you are from East to West first, because it is more downhill from West to East on the return.
