Derrick's Theory
Captain Derrick Washington is one of the four captains of the Timberland Tigers basketball team. Derrick has this theory: If he drinks water every 8 minutes, milk every 12 minutes, and coffee every 14 minutes, he will do better in that day's game. If Derrick woke up at 9:30am and drank all three drinks at 9:35am, what is the latest time he would have drank all three drinks at the same time if his game starts at 7:30pm?
Answer
5:59pmIt took 168 minutes, or 2 hours and 48 minutes, for Derrick to drink all of them at the same time again. If you repeatedly add 2 hours and 48 minutes to 9:35am, you'll find the last time prior to the game that all drinks were had at the same time was at 5:59pm.
