Answer:
In common scientific notation, any nonzero quantity can be expressed in two parts: sufficient whose absolute value is greater than or equal to 1 but less than 10, and a power of 10 by which the coefficient is multiplied. In some writings, the coefficients are closer to zero by one order of magnitude. In this scheme, any nonzero quantity is expressed in two parts: a coefficient whose absolute value is greater than or equal to 0.1 but less than 1, and a power of 10 by which the coefficient is multiplied. The quantity zero is denoted as 0 unless precision is demanded, in which case the requisite number of significant digits are written out
Answer:
His average speed was of 10.42 m/s
Step-by-step explanation:
We use the following relation to solve this question:

In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.
Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds.
This means that 
So his average speed was of:

His average speed was of 10.42 m/s
