Answer:
Sarah is asking each department head how long they can be without their primary system. Sarah is trying to determine the Recovery Time Objective (RTO) as this is the duration of time within which the primary system must be restored after the disruption.
Recovery Point Objective is basically to determine the age of restoration or recovery point.
Business recovery and technical recovery requirements are to assess the requirements to recover by Business or technically.
Hence, Recovery Time Objective (RTO) is the correct answer.
Since this traffic flow has a jam density of 122 veh/km, the maximum flow is equal to 3,599 veh/hr.
<u>Given the following data:</u>
- Jam density = 122 veh/km.
<h3>How to calculate the
maximum flow.</h3>
According to Greenshield Model, maximum flow is given by this formula:
![q_{max}=\frac{V_f \times K_i}{4}](https://tex.z-dn.net/?f=q_%7Bmax%7D%3D%5Cfrac%7BV_f%20%5Ctimes%20K_i%7D%7B4%7D)
<u>Where:</u>
is the free flow speed.
is the Jam density.
In order to calculate the free flow speed, we would use this formula:
![V_f =2 V\\\\V_f =2\times 59\\\\V_f=118\;km/hr](https://tex.z-dn.net/?f=V_f%20%3D2%20V%5C%5C%5C%5CV_f%20%3D2%5Ctimes%2059%5C%5C%5C%5CV_f%3D118%5C%3Bkm%2Fhr)
Substituting the parameters into the model, we have:
![q_{max}=\frac{118 \times 122}{4}\\\\q_{max}=\frac{14396}{4}](https://tex.z-dn.net/?f=q_%7Bmax%7D%3D%5Cfrac%7B118%20%5Ctimes%20122%7D%7B4%7D%5C%5C%5C%5Cq_%7Bmax%7D%3D%5Cfrac%7B14396%7D%7B4%7D)
Max flow = 3,599 veh/hr.

Answer: 5.36×10-3kg/h
Where 10-3 is 10 exponential 3 or 10 raised to the power of -3.
Explanation:using the formula
M =JAt = -DAt×Dc/Dx
Where D is change in the respective variables. Insulting the values we get,
=5.1 × 10-8 × 0.13 × 3600 × 2.9 × 0.31 / 4×10-3.
=5.36×10-3kg/h
