Answer 1

Answer:

The average speed of usain bolt in meter per second is $10\frac{5}{12}$.

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.

$speed=\frac{distance}{time}$

Given distance is 100 m and time in sec is

$9\frac{3}{5}=\frac{45+3}{5}=\frac{48}{5}$

The average speed in meter per second is

$speed=\frac{100}{\frac{48}{5}}$

$speed=\frac{500}{48}$

$speed=\frac{125}{12}$

$speed=10\frac{5}{12}$

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