Question: Stan is running a computer program to scan all the memory on a computer. When the program is ¾ done with its scan, it has 12 minutes left to run. How long does it take the computer program to scan the computer in total?

 

 

 

Answer:  48 minutes

 

 

Solution:  If the program is done scanning ¾ of the computer’s memory, then it has ¼ left. Since we know that it takes 12 minutes to scan ¼ of the memory, it takes 12 × 4 = 48 minutes to scan the whole thing.
