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:

h = 4.5 inches

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) h

We know A b1 and b2

20.25 = 1/2 (5+4)*h

20.25 = 9/2 h

Multiply each side by 2/9 to isolate h

2/9 * 20.25 = 2/9 *9/2 h

4.5 =h

Marizza181 [45]
Hi there! An equation for this problem would look something like

12d=75

Since the farmer can harvest 12 acres per day, the variable d represents days. 12 times the number of days it would take to harvest the field would equal 75.
