Answer 2

Answer:

Let's call the hours that remain x, and those which have passed y. Since there are 24 hours in a day, we have:

x+y=24  

Also, from the question, the hours that remain is 1/7 times the hours that have passed, so:

x=y/7  

Putting the value of x in the first equation gives:

y/7+y=24  

Multiplying though by 7 gives:

y+7y=24∗7  

8y=168  

y=21  

So the number of hours that have passed is 21, therefore it is 9 pm
