WebYes, instead of multiplying by time you can just plug the numbers into the equation: time = distance / rate (speed). In this case it would be: time = 720m / 3m per sec When you divide 720m by 3m/s the meters cancels out and you are then left with time which would be 240 seconds. This equation though is just a manipulation of rate = distance/time. Web11K Likes, 28 Comments - Joe! (@yankeelibrarian) on Instagram: "The Yankees didn’t bring back Andrew Benintendi.
