It will take Ahmad 12 hours to drive 864 miles
Step-by-step explanation:
- Step 1: Find the speed of Ahmad.
Distance = 360 miles
Time = 5 hours
⇒ Speed = Distance/Time = 360/5 = 72 miles/hour
- Step 2: Find the time required to drive 864 miles
⇒ Time = Distance/Speed = 864/72 = 12 hours
:) Well, I dunno about anyone else but this question makes my head spin!

Step-by-step explanation:
pretty simple not hard bub
For this case we propose a system of equations:
x: Variable that represents the amount of hours that Olivia's mother drove
y: Variable that represents the amount of hours that Olivia's father drove
So, we have:
![x + y = 14\\65x + 60y = 895](https://tex.z-dn.net/?f=x%20%2B%20y%20%3D%2014%5C%5C65x%20%2B%2060y%20%3D%20895)
From the first equation we have:
![x = 14-y](https://tex.z-dn.net/?f=x%20%3D%2014-y)
Substituting in the second equation:
![65 (14-y) + 60y = 895\\910-65y + 60y = 895\\-5y = 895-910\\-5y = -15\\y = \frac {15} {5}\\y = 3](https://tex.z-dn.net/?f=65%20%2814-y%29%20%2B%2060y%20%3D%20895%5C%5C910-65y%20%2B%2060y%20%3D%20895%5C%5C-5y%20%3D%20895-910%5C%5C-5y%20%3D%20-15%5C%5Cy%20%3D%20%5Cfrac%20%7B15%7D%20%7B5%7D%5C%5Cy%20%3D%203)
Thus, Olivia's father drove 3 hours.
![x = 14-3 = 11](https://tex.z-dn.net/?f=x%20%3D%2014-3%20%3D%2011)
Olivia's mother drove 11 hours.
Answer:
![(x, y) :( 11,3)](https://tex.z-dn.net/?f=%28x%2C%20y%29%20%3A%28%2011%2C3%29)
