Answer:
![B =102](https://tex.z-dn.net/?f=B%20%3D102)
![Y = 32](https://tex.z-dn.net/?f=Y%20%3D%2032)
Step-by-step explanation:
Solving (47):
To solve for B, we have:
--- sum of angles in a triangle
This gives
![B + 78 = 180](https://tex.z-dn.net/?f=B%20%2B%2078%20%3D%20180)
Collect like terms
![B =- 78 + 180](https://tex.z-dn.net/?f=B%20%3D-%2078%20%2B%20180)
![B =102](https://tex.z-dn.net/?f=B%20%3D102)
Solving (48):
To solve for Y, we have:
--- sum of angles in a triangle
This gives
![Y = 180 - X - Z](https://tex.z-dn.net/?f=Y%20%3D%20180%20-%20X%20-%20Z)
Where
-- angle on a straight line
Solve for X
![X=180 -W](https://tex.z-dn.net/?f=X%3D180%20-W)
![X=180 -100 = 80](https://tex.z-dn.net/?f=X%3D180%20-100%20%3D%2080)
So, we have:
![Y = 180 - X - Z](https://tex.z-dn.net/?f=Y%20%3D%20180%20-%20X%20-%20Z)
![Y = 180 - 80 - 68](https://tex.z-dn.net/?f=Y%20%3D%20180%20-%2080%20-%2068)
![Y = 32](https://tex.z-dn.net/?f=Y%20%3D%2032)
Since you are trying to figure out how many miles she can drive in 1 hour and you already have half of that hour, all you would need to do is double that number.
![\frac{4}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20)
×
![\frac{2}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B1%7D%20)
=
![\frac{8}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B5%7D%20)
Now, all you would need to do is simplify the answer.
![\frac{8}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B5%7D%20)
= 1
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
or 1.6
The answer would be, Suzy can drive 1
![\frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B5%7D%20)
or 1.6 miles in 1 hour.
I hope this helps!
To find out time interval δt we need to substract initial time from the final time. In this question first number in the coordinates representes time:
δt=50 - 0
δt= 50s
TIme interval is 50s.
