I think i get it, thank you! 

It's okay. I apologize once again for not responding to that post.

The answer to B is apparently 60. I cannot understand why though.

Sorry, I most likely missed his response. Additionally, this is from more than a year ago- I am unable to change anything.

I'm sorry. I was expecting to receive an email notification but did not get one, and I am not on this website 24/7. I did not intend to come off as unappreciative. 

As for the correct answers, the answer to part A is 20. A pair of white chairs must be separated by one red chair. The red chairs can be arranged like _ R _ R _ R _ R _ R _ with 6 spaces to put the white chairs. Then 6 choose 3 = 20. Part B is not so clear to me, so I'm not sure of the correct answer.

It's solving for the area of the green section. And I think I've got the answer now.

Oh okay, thanks!

May I ask how you got that?

Does this just depend on reasoning perhaps? I don't think there's anything complex, I simply got the answer by playing around but obviously that's not the correct way to solve it.

Yes, but I want to learn how to get to that answer :/

I'm pretty sure H is correct, as it's showing the same time at two different distances. It's not possible for one person to be at two different places at the same time. But thank you!

Oh okay! Thank you!

So would the length that the catcher throws be the diagonal of the diamond + 3?
