Ablue whale calf swam from miami, florida, to havana, cuba, a distance of 228 miles, in 12 hours 22 minutes. which is closest to the calf's average rate of speed, in feet per hour?

Step-by-step explanation:

You need to make the conversion from  miles to feet. Since:

You get:

Convert 22 minutes to hours.

Since:

You get:

Therefore, the time in hours is:

Now you must use the following formula:

Where "V" is the speed, "d" is distance and "t" is time.

You can identify that, in this case:

Therefore, substituting values into the formula, you get:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
