Karen is constantly trying to stop the raccoons from getting in her trash. The first lock she tries stalls them for 5 minutes. The next lock stalls them for 3 minutes less than three times as long as the first lock. When Karen tries both locks at once, it stalled the raccoons for five times as long as the second lock alone. How long is that? Let's be accurate as possible.

First find how long the second lock stalls them: 5 minutes * 3 - 3 minutes = 12 minutes. Then multiply that amount by 5 to find the total time the third lock stall the raccoon: 12 minutes * 5 = 60 minutes.
The answer: 60.
