Answer:
![x=\frac{7}{15}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B7%7D%7B15%7D)
Step-by-step explanation:
![5x-\frac{1}{5} =\frac{7}{3}](https://tex.z-dn.net/?f=5x-%5Cfrac%7B1%7D%7B5%7D%20%3D%5Cfrac%7B7%7D%7B3%7D)
![5x - \frac{3}{15} = \frac{35}{15}](https://tex.z-dn.net/?f=5x%20-%20%5Cfrac%7B3%7D%7B15%7D%20%20%3D%20%5Cfrac%7B35%7D%7B15%7D)
![5x - \frac{3}{15} + \frac{3}{15} = \frac{35}{15} + \frac{3}{15}](https://tex.z-dn.net/?f=5x%20-%20%5Cfrac%7B3%7D%7B15%7D%20%20%2B%20%5Cfrac%7B3%7D%7B15%7D%20%3D%20%5Cfrac%7B35%7D%7B15%7D%20%20%2B%20%5Cfrac%7B3%7D%7B15%7D)
![5x=\frac{35}{15}](https://tex.z-dn.net/?f=5x%3D%5Cfrac%7B35%7D%7B15%7D)
![\frac{5x}{5} } =\frac{\frac{35}{15}}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B5%7D%20%7D%20%3D%5Cfrac%7B%5Cfrac%7B35%7D%7B15%7D%7D%7B5%7D)
![x=\frac{7}{15}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B7%7D%7B15%7D)
This is direct proportion - it takes less time to run 15 miles than 50 miles. Show the comparison:

Answer:
17
Step-by-step explanation:
IQR = Q3 - Q1
1st Quartile: 13
3rd Quartile: 30
IQR = 30 - 13 = <u>17</u>
