Sorry. Altitude is in feet. As much as I'd like to do metric, for 7th graders, it seems easiest to use feet (they can grasp that concept better).

Math teacher in over his head :) Not so much "over my head" as I don't have as much time as I'd like to research the answers. My 7th grade honors class is doing a project on "How fast is the Space Shuttle in terms of Mach?" (My title, not theirs :) ). They didn't have too much trouble...
