Question

A class starts at 10:00 AM and ends at 1:27 PM. Four sessions of equal duration are held during this interval. After every period, a rest of 5 minutes is given to the students. The exact duration of each session is:

• A. 48 min
• B. 50 min
• C. 51 min
• D. 53 min

Hint:

Subtract total break time from the full duration, then divide the remainder by number of sessions.

Answer 1

The Correct Option is A

Step 1: Total time from 10:00 AM to 1:27 PM \[ = 3 \, \text{hours and} \, 27 \, \text{minutes} = 207 \, \text{minutes} \] Step 2: Total rest time After 4 sessions, rest happens 3 times: \[ \text{Rest time} = 3 \times 5 = 15 \, \text{minutes} \] Step 3: Total teaching time \[ 207 - 15 = 192 \, \text{minutes} \] Step 4: Duration per session \[ \frac{192}{4} = \boxed{48 \, \text{minutes}} \]
