My sub teacher today gave us a time problem on our homework. We haven't worked with time yet so I'm not quite sure I got it right:
Ed started work at 8:45 AM. He stopped for lunch at 12:00 PM and went back to work at 12:45 PM. He quit for the day at 6:15 PM. How long did Ed work this day?
I got 9 hr 85 min to start which is incorrect. I was then unsure if what to do next so I subtracted 985 from 60 and got 25 so I assumed I would do the same process as when you are simplifiying fractions (1 8/7 - 2 1/8) Please Explain.

Here's how I'd tackle this problem.

8:45 is 15 minutes before 9:00. 9:00 to 12:00 = 3 hours. 3 + 15 = 3:15

12:45 is 15 minutes for 1:00. 1:00 to 6:00 = 5 hours. 5 hours + 30 minutes = 5:30

5:30 + 3:15 = 8:45 = 8 hours and 45 minutes.
