A track and field athlete with a height of1.70m is participating in the100m sprint. At the finish line, a photographer stood by the finish line of the runway to take pictures.

If the displacement in the exposure time is x, there is a proportional relationship and HH = SX is obtained.

According to the definition of speed, V = XT = HSHT = 1.6× 10? 2×5× 10? 31.7×160m/s = 8.5m/s.

A: The sprint speed is 8.5 meters per second.
