can someone post the basic formula to convert TT times to speed. Thanks.

miles / hours

miles / (minutes x 60)
Huh?Kerry

So if I ride a 10 mile time trial in 25 minutes, my speed is 10/(25*60) = .0067? Perhaps you should double check your equation? Like (milesx60)/minutes ?

(Distance Times 60 Minutes) divided by (Actual time in minutes)

So for Example:

Distance 25 miles
Time 64.2 minutes
Speed would be (25 X 60)/64.2=23.36mph

But it's a handy bookmark.

Dude, I don't want to be mean, but if you are an adult and doesn't know how to convert time into speed, it's really sad?

MPH stands for Miles per Hour or (miles/hour)

Take your distance and divide it by the time. Be sure to convert minutes into hours.
Use dimensional analysis:
1 hr = 60 min
so if you have the time in minute.
mile/(min/60)=MPH
should give you MPH. For KPH just switch out Miles for Kilometers

Don't forget the seconds too. To add in the seconds use this formula

MPH=mile/(min/60+sec/3600)
