Answer:
56.7 mi/h
Step-by-step explanation:
The formula for average speed is:
Average Speed =
Thus we have:
Average Speed = mph
<em>Rounding to the nearest tenth, we have </em>
Average Speed = 56.7 mi/h

We deduce that:
An ellipse (oval shape) is expressed by the following equation:
where h is the x coordinate of the center and k is the y coordinate of the center. Furthermore, a is the horizontal distance from the center, and b is the vertical distance from the center. Lastly, c is the distance from the center to one of the foci (they are spaced apart equally).
We can find the foci by using
36 - 11 =
Since the k value in this case is 0, the y value of both foci are 0. Also, since h and k are both 0, we know the center of the ellipse is at the origin.
So the foci are (-5, 0) and (5, 0)
Hope this helps :)
