      Must be the Byrne factor! lol.. Anyway the times get turned into NBRA and they will post the final speed

        Does anyone have a speed chart that is all figured out for a 3/4 mile course or 2.25 miles.. Not a formula with variables

          Sorry, but v = d/t

              Dan, I believe those are incorrect times! One was 2:32.2 seconds (That would be 2 minutes 32.2 seconds). The other was 2:28.2 (that would be 2 minutes 28.2 seconds)

              I guess that is why NBRA gets the big bucks to do the calculations! Perhaps the calculator that I used from "the internet" is flawed.

                Is the calculator that I used. Perhaps it is not calculating correctly.

                  My bad, its:

                  Average speed = distance/time (Scalar quantity.)

                  and

                  Average velocity = *delta position/time (Vector quantity.

                    I have got to ask how 2 minutes and 32 seconds suddenly turns into 2 min 19 seconds... Just asking

                      2.32 minutes is the decimal equivalent of 2 minutes 19.2 seconds.


                      to get a decimal minute, divide the seconds (19.2) by number of seconds per minute (60). 19.2/60=.32

                        yes Kyle I agree with you if it was a decimal of a minute. But, it isn't! It is recorded in minutes, seconds and tenths.

                        Please read the time again, as an example the one time is:

                        A Hydro -

                        2 minutes 32 seconds plus 2/10th of a second

                        it is not a decimal of a minute as in .32 being 19.2 seconds.

                        2 : (colon not point) 32 . (point) 2

                        So if you wanted a decimal it would be 2 minutes plus 32.2/60 =2.54

                        For C-Hydro

                        2 minutes 28 seconds and 2/10th of a second

                        2 : 28 . 2

                        So if you wanted a decimal it would be 2 minutes plus 28.2/60= 2.47

                        Clear as mud now?
