Remark

You cannot give an answer to this unless you are give the fastest speed of a swimmer. That stat is not an easy one to decide upon. At what distance for example or do you eliminate distance? Since this is a college level question, I don't think it unreasonable that you have to research raw distance over fastest time.

The fastest speed I can find is 100 meters in 46.91 seconds.  That means that the actual speed of the swimmer is 100 meters / 46.91 = 2.132 meters / second.

Givens

Set up a proportion with the numbers found and given

Speed of ball / speed of swimmer = 21.12 / 1

Speed of ball = x

Solution

Speed of swimmer = 2.132 m/s

x / 2.132 = 21.12 / 1          Multiply Both sides by 2.132

x = 21.12 * 2.132 / 1

x = 45.02 m/s

Answer

45.02 m/s

Answer:

42.66s = 21.12 * 2.02\\   = 42.66 m/s m/s

Step-by-step explanation:

The fastest swimmer, Caeleb Dressel holds the record of 49.50 for 100m

Taking the distance and time, we can compute the velocity:

V = \frac{displacemnent}{time} \\= \frac{100m}{49.50s}\\= 2.02 m/s

The velocity (speed) of the fastest swimmer will be 2.02 m/s

A tennis ball will travel at 21. 12 times faster which is:

Answer:

  20n

Step-by-step explanation:

Multiply square feet per person times the number of persons to find square feet.

The units analysis looks like this:

\dfrac{\text{ft}^2}{\text{person}}\times \text{persons}=\text{ft}^2\\\\20\dfrac{\text{ft}^2}{\text{person}}\times n\,\text{persons}=20n\,\text{ft}^2
