Veronicas clock

Question

veronicas clock loses six minutes each hour. If the clock is set correctly at 12 o'clock noon, for what time should veronica set the alarm if she wants to awaken at 6 a.m. the next morning?

Answer 1

If the clock looses 6 minutes each hour, then when an hour of correct time passes, only 54 minutes will pass on the clock.  From 12 noon to 6 am, a total of 18 real-world hours pass.  The clock loses 6 minute for every one of those hours, so it would be 6 time 18 or 108 minutes behind.  108 minutes is 1 hour and 48 minutes so you would want to subtract 1 hour and 48 minutes from 6 a.m.     6 a.m. - 1 hour = 5 a.m. - 48 minutes = 4:12 a.m.

 

Set the alarm for 4:12 am  (and get a better clock for the future).
