My question is: Pete has to take a 10-minute walk down to the train station and then board a 1hr 20-minute train to LA. When should he leave if he cannot get to LA later than 0900 hours? (24-hr time) Your thoughts:

There are 60 minutes in an hour so 1 hour 20 minutes = (60 + 20) minutes = 80 minutes. He will spend a total of 80 + 10 = 90 minutes. 90 minutes is = (60 / 60) hours and 30 minutes = 1 hour 30 minutes = 0130 in 24 - hr time. He has to leave 0130 hours earlier than 0900 i.e. 0900 - 0130 = 0730 hours. The final answer: 730.
