Answer:
8 : 24 P.M
Step-by-step explanation:
Data provided in the question:
On December 1 bright star Procyon will just be rising on the eastern horizon at 10 P.M
Now,
we know that Stars rise 4 minutes earlier each night
Therefore,
24 days later i.e after 24 nights the total early time
= 24 days × 4 minutes per day
= 96 minutes
or
= 1 hour 36 minutes early
Hence,
on Christmas Day the star will rise at 1 hour 36 minutes early than 10 P.M
= 8 : 24 P.M
