MCQ - 77-11929

Correct Answer: A

Explanation:

To find the speed of the deer, you must have the distance traveled and the time.

The distance is found using the Pythagorean Theorem:

${\displaystyle C=\sqrt{A^2+B^2}}$

${\displaystyle C=\sqrt{A^2+B^2}}$

${\displaystyle C=\sqrt{{30}^2+{40}^2}}$

${\displaystyle C=\sqrt{2500}=50}$

The answer must be in miles per hour so the total miles are divided by the hours to get the final answer:

${\displaystyle \frac{miles}{hour}=\frac{50}{8}=6.25mph}$
