Correct option is D
Given:
Classes start at 8:25 am
Duration of each period = 35 minutes
Find the starting time of the 4th period
Solution:
The 1st period starts at 8:25 am
Time elapsed before 4th period = 3 periods
3 × 35 = 105 minutes
Convert 105 minutes:
105 = 1 hour 45 minutes
Now,
8:25 am + 1:45 = 10:10 am
Thus, Fourth period will start at 10:10 am
