26pi (103) in/min

convert it to miles/hr and the answer should be about 7.967 mi/hr

Distance traveled in a minute = (103*26) = 2678.

(2678 inches / 1 minute)(60 min/ hour) = 160680 inches per hour

(160680 inches / 1 hour)(1 mile / 63360 inches) = 2.536 mph
 
apprx 7.97 mph

26 in di is appx 81.68 in circumference.

103 rpm * 60 mins/h = 6180 rph

6180 * 81.68 = 504,782 in per hour is appx 7.97 mph

206 pi * 13 = 2678 pi inches / minute.

From here, you convert to inches per hour by

(2678*pi)*60
= 504791 inches / hour

Then, convert to miles / hour:

504,791 / (12 * 5280) = 7.97 miles per hour.
