At a movie theater, 360 people can see a particular movie over a period of 3 hours. At this rate, how many people can see this movie over period of 12 hours?

With this ratio in 12 h the amount of people that will watch the movie is 1,440.

Step-by-step explanation:

In order to compute how many people will see the movie in 12 hours we need to find the ratio per hour of people watching the movie. We were given the information that 360 people watched the movie in 3 h, to convert this value to people per hour we can divide the amount of people that watched the movie on that time by the total amount of time that passed. We have:

ratio = 360/3 = 120 people/h

We now multiply the ratio of people watching the movie by the length of time that we want to know, that is 12h. So we have:

amount of people = time*ratio = 12*120 = 1440
