Speed vs time

[LEN_LEEB@xxxxxxxxxxxxxxxxxxxxxxx]

     I wrote:
      Less time = higher actual speed, or speed = 60/time.
     
     As I look at it in print, I see my error: 
     
     It should be:    Speed = 60/time * 60 mph
     
     Where time is in seconds. ie, if the measured mile were completed in 
     55 seconds, the speed is then 60/55 * 60 mph = 65.45 mph
     Conversely if the mile were completed in 65 seconds, we get 55.38 mph
