Maryann can pick the lock on a cheap pair of handcuffs in 6 minutes and on an expensive pair of handcuffs in 8 minutes. If Maryann needs to rescue three of her friends who have expensive handcuffs on their hands and cheap handcuffs on their ankles, how long will it take for her to free all of them?
How long does it take Maryann to rescue one friend? ** First find the total time it takes Maryann to rescue one friend: 6 minutes + 8 minutes = <<6+8=14>>14 minutes
How long does it take Maryann to save all three friends? ** Then multiply the time to save one friend by the number of friends Maryann needs to save: 14 minutes/friend * 3 friends = <<14*3=42>>42 minutes
