ANSWER
144 minutes
Step-by-step explanation:
Felipe runs 5 miles in 60 minutes.
We want to know how long it will take him to run 12 miles at that same rate.
To do this we will compare and make the unkown x:
5 miles = 60 minutes
12 miles = x
Now, cross multiply:
x * 5 = 12 * 60
It will take Felipe 144 minutes to run 12 miles at that rate.
