In 2009, usain bolt set the world record for sprinting 100 m in approximately 9 and 5/ 3 seconds. find his average speed in meters per second.

The average speed of Usain Bolt is 9.38 m/s

Step-by-step explanation:

It is given that,

Distance covered by Usain Bolt, d = 100 m

Time taken,

Let v is the average speed of Usain Bolt. The total distance covered divided by total time taken is called the average speed of an object. Mathematically, it  is given by :

v = 9.38 m/s

So, the average speed of Usain Bolt is 9.38 m/s. Hence, this is the required solution.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
