Step-by-step explanation:
![\frac{3x}{x + 1} \div (x + 1) \\ \\ = \frac{3x}{x + 1} \times \frac{1}{(x + 1) } \\ \\ = \frac{3x}{ {(x + 1)}^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%7D%7Bx%20%2B%201%7D%20%20%5Cdiv%20%28x%20%2B%201%29%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B3x%7D%7Bx%20%2B%201%7D%20%20%5Ctimes%20%20%20%5Cfrac%7B1%7D%7B%28x%20%2B%201%29%20%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B3x%7D%7B%20%7B%28x%20%2B%201%29%7D%5E%7B2%7D%20%7D%20)
To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer
