Question

In 25 minutes 300 customers entered the attraction. At this rate how many would enter in an hour?

Answer 1

Use proportion in this problem:

Let x be a number of customers who entered in an hour. Then write a proportion:

$$25/60=300/x$$

where 60 is the number of minutes in an hour.

Then solve this equation:

$$x=(300*60)/25=720$$

this is the answer: 720 customers would enter in an hour.
