Answer:

The average speed of usain bolt in meter per second is [tex]10\frac{5}{12}[/tex].

Step-by-step explanation:

It is given that usain bolt set the world record for sprinting 100 m in approximately 9 3/5 a second.

Formula for average speed.

[tex]speed=\frac{distance}{time}[/tex]

Given distance is 100 m and time in sec is

[tex]9\frac{3}{5}=\frac{45+3}{5}=\frac{48}{5}[/tex]

The average speed in meter per second is

[tex]speed=\frac{100}{\frac{48}{5}}[/tex]

[tex]speed=\frac{500}{48}[/tex]

[tex]speed=\frac{125}{12}[/tex]

[tex]speed=10\frac{5}{12}[/tex]

Therefore the average speed of usain bolt in meter per second is [tex]10\frac{5}{12}[/tex].
