A virus scanning program is checking every file for viruses. It has completed checking 40% of the files in 300 seconds. How long should it take to check all the files?
I am not sure how to set this problem up, can someone please help!
40% = 40/100
40/100 = 300/x
Solve for x.
I hope this helps. Thanks for asking.
