Question

Every year, new records in track and field events are recorded. Let's take a 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

V=r/t
Speed equals displacement over the time

V=100/9.92=10.08ms^-1

Answer 2

Answer: His average speed (in m/s) for the race was 10.08 m/s

Step-by-step explanation:

Given data

Total distance traveled , D= 100 meter

Total time taken , T= 9.92 seconds

>The average speed(
`V_(avg)` ) of an object is the total distance traveled by the object divided by the total time taken to cover that distance .i.e.,

`V_(avg)=(D)/(T)=(100)/(9.92)\, (m)/(s)=10.08\: (m)/(s)`

Thus his average speed (in m/s) for the race was 10.08 m/s
