Tick Tock
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?
