Answer:
9:38am
Step-by-step explanation:
Given the elapsed time of 30 minutes, or the time since start time, we can count backwards to find the original start time. Since the ending time is 10:08am, if we subtract 8 minutes to 10:00am, then 30 - 8 = 22, which means the start time was 22 minutes before 10:00am, or 9:38am.
