To get his (average) speed in mph, you just need to divide the distance in miles by the time in hours.
So first you need to convert 2:09:21 into a decimal number of hours.
1 minute is 1/60 hour,
1 second is 1/3600 hour.
So 9 minutes 21 seconds is 9/60 + 21/3600 hours
= 540/3600 + 21/3600
= 561/3600
= 0.1558 hours (approx)
So the total time was 2.1558 hours.
Hence the average speed was 26/2.1558, which is approx 12.06 mph.
