The clock in my lounge room is 10 minutes slower than the clock on my phone, which is 6 minutes slow. My tram always leaves 6 minutes early, although it is scheduled for 8:55am. It takes me 20 minutes to get to the tram stop.
What time must I leave, according to my lounge room clock, in order to catch my tram?
Answers & Comments
Answer: earlier than 8:13am
Step-by-step explanation:
Tram leaves 8:49, which is 6mins earlier than it supposed to go
8:49 minus 20 minutes walk is 8:29
8:29 - 6mins slower on phone and - 10 minutes slower on lounge room,
8:29 minus 6minutes minus 10 minutes is 8:13 am
