Answer:
or 120.8 miles per hour
Step-by-step explanation:
We first convert the distance into an improper fraction to facilitate calculation.
Average speed
= distance/time
= miles per hour
= miles per hour
= miles per hour
= miles per hour or 120.8 miles per hour

<u>Step 1: Define</u>
Point A(-2, -4)
Point B(2, 4)
<u>Step 2: Find slope </u><em><u>m</u></em>
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>

Assuming that there are no discrepancies in the problem (foot length; crossbar width; etc.)
We can use the tangent function of the angle.
tan(x)=25/15
(move the “tan”)
x=arctan(25/15)
x = 59.04°
