(18 x 5280) x (1/56 x 60)/5280 =19.28 mph

Math lesson #1

Speed = Distance / Time
Hence the term miles per hour

Distance = 18 miles

Time = (well this needs to be in hours) so 56/60=.933

So speed would be 18/.933 which = 19.29 miles per hour

For any info relating to average speed, distance travelled, etc. use the formula "D = ST", where D is Distance, S is Speed, T is Time in hours. If you have two of the numbers you can always find out the third, e.g., D/T = S.

For your example, D=18 miles, T=.93 hours.

18/.93 = 19.35 mph

miles/(hours+(minutes/60)+(seconds/3600))

This is the formula I use in my spreadsheet bikelog. Lets say you rode 25 miles in 1:21:15

25/(1+(21/60)+(15/3600))=18.46....

Buy a cycle computer. Then you won't have do any calculations.
or forget the computer and pay attention in 3rd grade math.Steve_0
