What time must I leave, according to my lounge room clock, in order to catch my tram?
8:13am
The Clock Situation
The clock in my lounge room is 10 minutes slower than my phone, which is already 6 minutes slow. This means that the actual time according to my lounge room clock is 16 minutes behind the correct time. Additionally, my tram always leaves 6 minutes early, despite being scheduled for 8:55 am. It takes me 20 minutes to get to the tram stop. To calculate the exact time I must leave according to my lounge room clock, we need to do some math.
Calculating the Departure Time
To account for the discrepancies in time between my lounge room clock and the actual time, we need to add the total delay. The lounge room clock is 16 minutes behind the correct time, and the tram leaves 6 minutes early, totaling 22 minutes. Add the 20 minutes it takes for me to get to the tram stop, and we have a total of 42 minutes that need to be adjusted for.
Actual Departure Time = Scheduled Tram Time - Total Delay
Actual Departure Time = 8:55 am - 42 minutes = 8:13 am
Therefore, according to my lounge room clock, I must leave at 8:13 am in order to catch my tram. This calculated time accounts for the discrepancies in time between my lounge room clock, phone clock, and the early departure of the tram. By leaving at 8:13 am based on my lounge room clock, I should be able to catch my tram at the scheduled time of 8:55 am.
