Help!
At 11 o'clock, I set my alarm to go off 50 minutes later.
I need to leave at that time to go to my appointment.
Unfortunately, my clock was 20 minutes slow.
The time of my appointment had been moved up by 15 minutes.
So it wouldn't take me 35 minutes to get there, but 15 minutes less.
Questions:
What time did I arrive?
Was I on time, early, or late for my appointment?
Answer:
1.
Original Plan:
- Set alarm at 11:00 AM to go off 50 minutes later
(11:50 AM).
- Leave at 11:50 AM.
- Travel time: 35 minutes.
- Appointment time: 12:25 PM.
2. Actual Situation:
- Clock is 20 minutes slow, so alarm goes off at
12:10 PM (real time).
- Appointment moved up by 15 minutes to 12:10 PM.
- Travel time reduced by 15 minutes to 20 minutes.
3. Arrival Time:
- Leave at 12:10 PM.
- Travel time: 20 minutes.
- Arrival time: 12:30 PM.
So, I arrived at 12:30 PM, which means I was 20 minutes late for my
appointment.
