The answer is -4 2/3
Explanation : The elevator is at 0, and went below ground level 90 feet, that would be -90, then it went up 20 feet, which would be -90 + 20 = -70
-70 ft / 15sec = - 4 2/3
I am not sure about the ground level and negative difference but that it is what I was taught. Below ground level is negative and above is positive. Therefore the elevator traveled up and it traveled -4 2/3 per second.
It so either 4 2/3 or - 4 2/3 but pretty sure it is - 4 2/3.

Answer:
![q = \frac{s -4p}{4}\\](https://tex.z-dn.net/?f=q%20%3D%20%5Cfrac%7Bs%20-4p%7D%7B4%7D%5C%5C)
Step-by-step explanation:
![s = 4p +4q \\ 4p +4q = s \\ 4p +4q -4p = s -4p \\ 4q = s - 4p \\ \frac{4q}{4} = \frac{s -4p}{4} \\ q = \frac{s -4p}{4}](https://tex.z-dn.net/?f=s%20%3D%204p%20%2B4q%20%5C%5C%204p%20%2B4q%20%3D%20s%20%5C%5C%204p%20%2B4q%20-4p%20%3D%20s%20-4p%20%5C%5C%204q%20%3D%20s%20-%204p%20%5C%5C%20%5Cfrac%7B4q%7D%7B4%7D%20%3D%20%5Cfrac%7Bs%20-4p%7D%7B4%7D%20%5C%5C%20q%20%3D%20%5Cfrac%7Bs%20-4p%7D%7B4%7D)
Answer:
Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.
Step-by-step explanation:
Triangular Proportionality Theorem states that:
- If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.
Let us consider the triangle ΔABC as shown in attached figure.
If
║![AC](https://tex.z-dn.net/?f=AC)
then
![\frac{BD}{DA} = \frac{BE}{EC}](https://tex.z-dn.net/?f=%5Cfrac%7BBD%7D%7BDA%7D%20%3D%20%5Cfrac%7BBE%7D%7BEC%7D)
Therefore, Triangle Proportionality Theorem is defined by a line parallel to one side of a triangle divides the other two sides proportionally.
