Time frame = \(1:00pm\) to \(3:52pm\)
There are four afternoon class periods with \(4\) minutes between periods.
Period 1 - 4 min break - Period 2 - 4 min break - Period 3 - 4 min break - Period 4
Total time = \(2\) hr \(52\) min \(= 172\) mins
Total breaks are \(3\) so total break time = \(3 * 4 = 12\) min
Remaining time \(= 172 - 12 = 160\) min
Time for each period \(= \frac{160}{4} = 40\) min
Answer B
