There is no RAW answer for this in the books, so you have to calculate it.
However you have already supplied the necessary information to calculate these in the speed chart provided under Travel Pace. Of note: 1 mile = 5280 feet.
From the chart we assume one day of travel is 8 hours of actual travel:
Fast = 665 ft per minute / 7.5 miles per hour / 60 miles per day
Normal = 500 ft per minute / 6 miles per hour / 45 miles per day
Slow = 335 ft per minute / 4 miles per hour / 30 miles per day
The values here have been rounded to the nearest half. The fast and slow pace are set based on Travel Pace at 1/3 plus or minus normal speed.
