A machine produces 440 bolts in 48 minutes. At the same rate, how many bolts would be produced in 30 minutes?

1 answer:

3 0

The units you want is $\frac{bolts}{min}$ , so you set up the following equation:
$\frac{440\ bolts}{48\ mins} = \frac{x}{30\ mins} \\
440*30=48*x\\
13200=48x\\
x=\frac{13200}{48}=275 \frac{bolts}{min}$
