Question

Every year, new records in track and field events are recorded. Let's take an historic look back at some exciting races.

In 1989, Carl Lewis established a world record when he ran the 100. meter dash in 9.92 seconds. What was his average speed (in m/s) for the race? Remember to include your data, equation, and work when solving this problem.

Answer 1

100 meters in 9.92 seconds,
=distance/time
=100m/9.92s
=10.0806 m/s

Answer 2

Average velocity = 10.08 m/s

Step-by-step explanation:

Given

Length of the track d = 100 m

Duration of the run t = 9.92 s

Solution

`Velocity = (Distance)/(Time) \\\\Velocity = (100)/(9.92) \\\\Velocity = 10.08 m/s`
