Respuesta :

Taking into account the definition of speed, the average speed of the fastest man in the world is 16.35 miles per hour.

Definition of speed

Speed can be defined as the amount of space traveled per unit of time with which a body moves.

That is, the speed is associated with the change of position of an object in space within a certain amount of time and can be calculated using the expression:

speed= space traveled÷ time

Average speed of Bolt

In this case:

  • space traveled= 100 meters= 0.0621371 miles (being 1 m= 0.000621371 miles)
  • time= 13.75 seconds= 0.0038 h(being 3600 s= 1 h)

Replacing these values ​​in the definition of speed:

speed=0.0621371 miles÷ 0.0038 h

Solving:

Speed= 16.35 miles per hour

In summary, the average speed of the fastest man in the world is 16.35 miles per hour.
