Abee beats its wings 250 times each second. what is the average time for a single beat of a bee's wing?

for each second the bee beats its wings 250 times.

we are asked to find the average time taken for a single beat of a bees wing

the time taken for 250 beats - 1 second

average time for a single beat - 1 second/ 250 beats = 1/250 seconds/beat

answer is 0.004 seconds per beat

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
