Final answer:
To solve this time-based problem, we adjust the departure time from EST to PST by subtracting 3 hours, making it 10:10 AM PST. We then subtract this adjusted departure time from the arrival time to determine the duration of the trip, which is 10 hours and 19 minutes.
Step-by-step explanation:
To solve the problem of departing at 1:10 PM EST and arriving at 8:29 PM PST, we need to consider the difference in time zones between Eastern Standard Time (EST) and Pacific Standard Time (PST). EST is 3 hours ahead of PST. Therefore, if one departs at 1:10 PM EST, to find the equivalent PST, we subtract 3 hours from the EST departure time.
1:10 PM EST - 3 hours = 10:10 AM PST
Once we've adjusted the departure time to PST, we can calculate the duration of the trip. Assuming no date change during travel, if the arrival time is at 8:29 PM PST on the same day, we can subtract the adjusted PST departure time from the PST arrival time to find the duration:
8:29 PM PST - 10:10 AM PST = 10 hours and 19 minutes
The traveler has been in transit for 10 hours and 19 minutes, departing at 10:10 AM PST and arriving at 8:29 PM PST.
