Right, but they're not equal. You go more slowly on rising terrain, so
you spend more time for the same distance. That makes it unequal with
respect to speed (which is distance over *time*) even if there is the
same amount of it.


Your calculation makes no sense. You averaged three averages together
even though each individual average was for a different amount of
time. This is just as wrong as averaging three batting averages
together even though each was for a different number of at bats. The
result is *NOT* the average for the total set.

In the real world, 5280 * .172 = 908 feet and is quit significent if you are
in the shape I'm in.
Three football fields make a big difference.

In the world of math that is a wrong answer.
