Usain Bolt is considered to be the fastest person on earth. He holds the record for the fastest 100 m
(meters), which he ran in 9.58 s (seconds) in 2009. We'll assume that Bolt ran the race at a constant speed.

Sagot :

Using the relation between velocity, distance and time, it is found that the equation that describes a speed greater than Bolt's record-breaking speed in 2009 is:

  • [tex]v > \frac{100}{9.58}[/tex]

What is the relation between velocity, distance and time?

  • Velocity is distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex]

In this problem:

  • He runs 100 meters, hence [tex]d = 100[/tex].
  • He runs the 100 meters in 9.58 seconds, hence [tex]t = 9.58[/tex].

Hence, his velocity is:

[tex]v = \frac{d}{t} = \frac{100}{9.58}[/tex]

A velocity greater than his velocity is:

[tex]v > \frac{100}{9.58}[/tex]
