The correct label could be MN or NM
It doesn't matter because the line could be going left or right.

Given:
Scott can run 20 km in 85 minutes.
To find:
How long will it take Scott to run 52 km?
Solution:
Let x be the number of minutes it will take him to run 52 km.
We know that,
![Speed=\dfrac{Distance}{Time}](https://tex.z-dn.net/?f=Speed%3D%5Cdfrac%7BDistance%7D%7BTime%7D)
Using this formula, we get
...(i)
...(ii)
Equating (i) and (ii), we get
![\dfrac{20}{85}=\dfrac{52}{x}](https://tex.z-dn.net/?f=%5Cdfrac%7B20%7D%7B85%7D%3D%5Cdfrac%7B52%7D%7Bx%7D)
![20\times x=52\times 85](https://tex.z-dn.net/?f=20%5Ctimes%20x%3D52%5Ctimes%2085)
![20x=4420](https://tex.z-dn.net/?f=20x%3D4420)
Divide both sides by 20.
![x=\dfrac{4420}{20}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B4420%7D%7B20%7D)
![x=221](https://tex.z-dn.net/?f=x%3D221)
Therefore, it will take 221 minutes to run 52 km.
