There are runners in a race. How many ways can the runners finish first, second, and third? There are nothing different ways that the runners can finish first through . (Type a whole number.)

See Explanation Below

Step-by-step explanation:

Your question seem incomplete as the number of runners is omitted; However, I'll give a general guideline you can follow to solve questions like this

Assume that the number of runner is n;

The first position can be occupied by n persons

The second position can be occupied by n - 1 persons

The third position can be occupied by n - 2 persons

Now, let's assume n is 10

What if there are 50 runners?

You still apply the same logic and procedure;

This means that n = 50

What if there are just 8 runners?

This means that n = 8

So, whatever the number of runner is, just follow the steps I highlighted; you'll get your answer.

jml angle lkj & angle mj = lm

it would rotate about 180 degrees.
