Answer:</h2>
<u><em>The machine will be able to install 1600 bolts in 2 hours</em></u><em>.</em>
<h2>
Step-by-step explanation:</h2>
<h3>1. Create a rule of 3.</h3>
<em>A rule of is basically saying "I can to this, with this much. How much can I do with that much?"</em>
<em>In this case, the machine can install 240 bolts in 180 minutes, how many can it install in 2 hours?</em>
<em>Before creating a rule of 3, we're going to have to convert 2 hours to minutes, because the work rate of the machine is given in minutes. Let's go ahead and do that:</em>
2 hours * 60= 120 minutes.
<em>Now, let's create our rule of 3.</em>
<em>18 minutes -------> 240 bolts</em>
<em>120 minutes -----> x</em>
<em>x= (120 * 240 bolts) / 18 minutes</em>
<em>x= 1600 bolts.</em>
