What is the mystery behind the discrepancy in time between the two clocks and how can it be solved?
The student's question requires calculations related to time, including adding and subtracting measures of time and dealing with the accuracy of timekeeping devices.
Understanding the Time Discrepancy
When the student left home:
- Student's clock: 14:02
- Friend's clock: 14:25
The initial time difference between the two clocks was 23 minutes. This indicates that the student's clock was running slow by 23 minutes compared to the friend's clock.
When the student left the friend's house:
- Friend's clock: 15:08
- Student's clock: 15:56
Upon returning home, the time on the student's clock was 15:56 while the friend's clock showed 15:08. This indicates that the student's clock had advanced by 48 minutes during the round trip.
Solving the Mystery
To solve the mystery behind the time difference, we need to:
1. Calculate the total time taken for the round trip by the student.
2. Determine the actual time difference between the two clocks.
3. Adjust the student's clock to the correct time.
Calculations:
- Time taken for the round trip: 15:56 - 14:02 = 1 hour 54 minutes
- Actual time difference between the clocks: 48 minutes (15:08 - 14:20)
- Adjusted time for the student's clock: 15:56 - 48 minutes = 15:08
By adjusting the student's clock back by 48 minutes, we have corrected the discrepancy and aligned it with the friend's clock.
This mystery showcases the importance of understanding time calculations and the accuracy of timekeeping devices in daily life scenarios.
