I don’t understand how 3rd question is wrong
It seems like a tricky question. The first time I try to solve it, I think I made the same mistake you did. I don’t know if it is the same mistake but I made a mistake 😂
I looked at the nine minutes in the beginning and then noticed the six minutes and I noticed that would seem to be some people spent six minutes downloading the update even though they were not within three minutes of each other.
I assumed that since there were people who were within three minutes of each other who spent six minutes and people who were not within minutes of each other who spent six minutes then the answer would be “no”
however, if you examine all of the six minute downloads, all of them were for people who were within three minutes of someone else. It doesn’t have to be only three minutes down or three minutes up. It could be in any direction and based on that the answer is indeed “Yes”
