We are trying to find the average speed of the plane, which is mph, or
. Using proportions, we can find the average speed of the plane in mph:

- Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that
.

- Multiply the entire equation by


- Divide both sides of the equation by
to clear both sides of the mile unit
The average speed of the plane is 300 mph.
One way is to move the 4 to other side so it would be x = 13 - 4 and that's x = 9
what i did to get my answer was 13*6*6 because the whole circle is 12 and so i got 468.
Answer:
216 sq. units
Step-by-step explanation:
From the figure, we can see that only one pair of opposite angles are equal. So, the quadrilateral is a kite.
Formula to find the area of a kite:
Area, A = 
where,
and
are the lengths of the diagonals.
Here,
units.
And,
units.
Therefore, the area A = 
= 
= 216 sq. units which is the required answer.
