A friend says to you, “I’m the fastest runner in my class because I can run four miles without stopping.” Explain to your friend why her statement doesn’t make sense.

Just because they can run doesn't mean they are fast

Explanation:

you could take a day to run across a football field, or you can take 5 minutes, which is faster?

You're friend in this equation has little to no braincells so they would have trouble seeing that running the length of a football field in five minutes is faster than a day, however, if they also said they did it in less than five minutes then it would mean your friend is fast
