Equation to determine time over distance (sprints)


So I use my GoPro for a lot of training purposes and was wondering if anyone has experience in the equation to determine time from a certain distance. I’ve moved back to the 90 ft base to base sprints and found somewhere on the internet that if you divide frames by frame rate of your camera you get time?




the camera captures a series of still images that are played at a constant rate, so if you know the number of frames and the frame rate of your recording device you can get a fairly accurate time.
