8.75 inches
5 divided by 4 is 1.25
1.25 x 3 = 3.75
3.75 + 5 = 8.75
Answer:
1.50$
Step-by-step explanation:
Answer:
B:3=a(-1-6)(-1+5)
Step-by-step explanation:
The zeroes are 6 and -5 so we can write it as y=a(x-6)(x+5)
Now the point(-1,3) is on the line so substituting for x and y:
3=a(-1-6)(-1+5)

For this case we have to write the equation of the position of each one.
We have then:
For the robber:
![r = 14t](https://tex.z-dn.net/?f=%20r%20%3D%2014t%20)
For the marshall
:
![r = 16 (t- (\frac{20}{60}))](https://tex.z-dn.net/?f=%20r%20%3D%2016%20%28t-%20%28%5Cfrac%7B20%7D%7B60%7D%29%29%20)
![r = 16 (t-\frac{1}{3})](https://tex.z-dn.net/?f=%20r%20%3D%2016%20%28t-%5Cfrac%7B1%7D%7B3%7D%29%20)
By the time the marshall reaches the robber we have:
![14t = 16 (t-\frac{1}{3})](https://tex.z-dn.net/?f=%2014t%20%3D%2016%20%28t-%5Cfrac%7B1%7D%7B3%7D%29%20)
From here, we clear the time.
We have then:
![16t - 14t = \frac{16}{3}](https://tex.z-dn.net/?f=%2016t%20-%2014t%20%3D%20%5Cfrac%7B16%7D%7B3%7D%20)
![2t = \frac{16}{3}](https://tex.z-dn.net/?f=%202t%20%3D%20%5Cfrac%7B16%7D%7B3%7D%20%20)
![t =\frac{8}{3}](https://tex.z-dn.net/?f=%20t%20%3D%5Cfrac%7B8%7D%7B3%7D%20)
![t = 2.7 h](https://tex.z-dn.net/?f=%20t%20%3D%202.7%20h%20)
Answer:
it takes the marshall to catch up to the robber about 2.7 hours.
