Step-by-step explanation:
Starting Time= 9:00 AM
and according to the condition, it looses 15mins per hour, so total time to be taken into account each hour is 45mins.
from 9 to 10AM (1hr),
it'll show-9:45AM
from 10AM to 11AM(1hr),
it'll show- 9:45 +45mins= 10:30AM
so we need to show for only 30mins more
from 11AM-12(1hr),
it'll show-10:30 +45mins= 11:15AM
but,, we want the time for EXACT 11:00AM.
So, in your equation: 45v==60r
(v=virtual time, r=real time
when we want 30mins,
45v×2/3= 60r×2/3
30v=40r
Therefore, we need 40real mins more, i.e, 11AM+40mins=11:40AM
Hope this helps, if you find the solution a bit tricky, you can ask in comments.
