Question

If Sasha can run 720 yards in 4 minutes, how many feet can she run in 15 seconds?

Answer 1

Okay so you're trying to find the unit rate of 720yds/4min. If you divide 720 by 4 you will have the unit rate as 180yds/1 min or 60 sec then if you divide 180 and 60 by 4 again you will get the answer of 45yds/15sec.
