Randy has a lot of homework tonight. He needs to work for 45 minutes on social studies, 40 minutes on science, and 1 hour and 15 minutes on math. It will also take him 10 minutes to get ready for bed. If he wants to be in bed at 10:00, what time does he need to start his homework?
-------------------
Homework+ time = (45 + 40 + 75 + 10)/60 = 170/60 = 17/6 = 2 hrs 50 min
----
10:00 - 2hrs 50 min = 7:10PM
