How many people can finish first?

OpenStudy (anonymous):

I was thinking multiplying but 50 isn't there

OpenStudy (anonymous):

Can finish first?

OpenStudy (anonymous):

And after the winner finishes, how many people can finish second?

OpenStudy (anonymous):

Do I divide?

OpenStudy (anonymous):

I don't get it

OpenStudy (anonymous):

Great. I'm trying to help by asking these questions. How many people can finish first?

OpenStudy (anonymous):

Umm.. What steps do I do?

OpenStudy (anonymous):

How many people can possibly finish first?

OpenStudy (anonymous):

Let see... 20?

OpenStudy (anonymous):

I really don't know..

OpenStudy (anonymous):

How many people are in the race?

OpenStudy (anonymous):

25

OpenStudy (anonymous):

So 25 people could possibly win the race. Right?

OpenStudy (anonymous):

Now, after the winner has crossed the finish line, how many people are there that could possibly finish second?
