<p>Any short cuts? I tried the long way and I got it wrong, I saw the answer and I plug in and it didnt end at that time</p>

<p>Session I
Break
Session II
Lunch
Session III
Break
Session IV </p>

<p>In the scheldule above each session is to be 1 1/2 hours long, each break is to be 1/4 hours, lunch is to be 1 hour long. If session IV ends at 4:30 PM at what time does session I begin?</p>

<p>Answer: 9:00am</p>

<p>Starting at Sess 4, subtract 1.5 hours = 3 PM.

  • 15 minutes for break= 2:45 PM.
    -1.5 hours for Sess 3= 1:15 PM
    -1 hour for lunch= 12:15 PM
    -1.5 hours for session 2= 10:45 AM
  • 15 minutes for break = 10:30 AM.
    -1.5 hours for sess 1= 9 AM</p>

<p>remember that 1/4 of an hour is 15 minutes.</p>

<p>Shortcut.</p>

<p>Session(s) = 90 min
break(b) = 15 min
lunch(l) = 60 min</p>

<p>4S+2B+L = 450 min</p>

<p>450/60 = 7.5 hours.</p>

<p>7.5 hours before 4:30 = 9:00.</p>
