Question

Sid loaded 7 trucks every 42 minutes. At that rate, how many would heload in 12 minutes?

Answer 1

2 trucks

Step-by-step 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:

`\begin{gathered} \Rightarrow\text{ x =}\frac{7\cdot\text{ 12}}{42} \\ x\text{ =2 trucks} \end{gathered}`

Therefore, Sid will load 2 trucks in 12 minutes.
