To find the speed of the fastest human in body lengths per second, we need to convert their speed from meters per second to body lengths per second. Here are the steps to calculate the speed:

1. Determine the number of body lengths in 100 meters.
   - Divide the distance of 100 meters by the height of the person, which is 1.95 meters.
   - 100 meters / 1.95 meters = approximately 51.28 body lengths.

2. Convert the time taken to run 100 meters from seconds to seconds per body length.
   - Divide the time of 9.63 secon...
