ANSWER
2 trucks
EXPLANATION
Sid loaded 7 trucks every 42 minutes.
We are going to treat this as a proportional relationship.
Let the number of trucks Sid will load in 12 minutes be x.
So, we have that:
42 minutes = 7 trucks
=> 12 minutes = x trucks
We can cross-multiply:
=> 42 * x = 7 * 12
Divide both sides by 42:
[tex]\begin{gathered} \Rightarrow\text{ x =}\frac{7\cdot\text{ 12}}{42} \\ x\text{ =2 trucks} \end{gathered}[/tex]Therefore, Sid will load 2 trucks in 12 minutes.
