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. DS |
