We rode the MKT from Columbia to the Katy and back last Saturday. The downhill trip averaged 12.5 mph, while the return (uphill) trip averaged 11 mph. Personally, I like to take a break every hour or so. My guess for your trip would be about 3 to 4 hours depending on how fast you pedal and how many breaks you take.
