The second one is the correct answer
Answer:
![Empty = \frac{5}{12}](https://tex.z-dn.net/?f=Empty%20%3D%20%5Cfrac%7B5%7D%7B12%7D)
Step-by-step explanation:
Given
![Water = \frac{1}{3}](https://tex.z-dn.net/?f=Water%20%3D%20%5Cfrac%7B1%7D%7B3%7D)
![Oil = \frac{1}{4}](https://tex.z-dn.net/?f=Oil%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
Required
The fraction that is empty
The constituent of the water can be represented as:
![Water + Oil + Empty = 1](https://tex.z-dn.net/?f=Water%20%2B%20Oil%20%2B%20Empty%20%3D%201)
Make Empty the subject
![Empty = 1 - Water - Oil](https://tex.z-dn.net/?f=Empty%20%3D%201%20-%20Water%20-%20Oil)
Substitute values for Water and Oil
![Empty = 1 - \frac{1}{3} - \frac{1}{4}](https://tex.z-dn.net/?f=Empty%20%3D%201%20-%20%5Cfrac%7B1%7D%7B3%7D%20-%20%5Cfrac%7B1%7D%7B4%7D)
Take LCM
![Empty = \frac{12 - 4 - 3}{12}](https://tex.z-dn.net/?f=Empty%20%3D%20%5Cfrac%7B12%20-%204%20-%203%7D%7B12%7D)
![Empty = \frac{5}{12}](https://tex.z-dn.net/?f=Empty%20%3D%20%5Cfrac%7B5%7D%7B12%7D)
Speed milles 120 ÷ 105 min = 1.14 milles
1.14 x 60 = 68.4 milles per hour
