talk to them, play video games with them, just hang out
I believe more of a mysterious tone but im not for sure
Did he realize his mistake? - interrogative
He didn't realize his mistake. - Negative
If I understand the question right I would believe it to be 5 miles an hour because the course is a mile and he ran a mile in 12 minutes. We know an hour is 60 minutes so we have to divide the number of minutes he is talking from the hour. 60 divided by 12 is 5 so if he is running a mile every 12 minutes then he is running 5mph
