Answer 1

Answer:

9 pm

Step-by-step explanation:

The remaining hours of the day are equal to one seventh of those that have passed. What is the time?

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.
