A runner ran 2/3 of a 5 kilometer race in 21 minutes. They ran the entire race at a constant speed.

1. How long did it take to run the entire race?

2. How many minutes did it take to run 1 kilometer?

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
