An identity thief is trying to break into someone's computer that is protected by a 4-digit passcode where numbers can repeat. The thief knows that the first digit is 2 and the last digit is 7,8 or 9 . If the thief can attempt 60 passcodes per hour, what is the longest time in hours that they could take to break into the computer?
