Question

In training for a swim meet, Logan swam 750 meters in \large\frac{1}{3 of an hour. His swimming partner , Mila, swam \frac{2}3} of Logan’s distance in \frac{1}{4} of an hour. Fill in the blanks to compare Mila’s and Logan’s swimming speeds. 1. What is Logan’s average swimming speed? Show your work.

Answer 1

The relationship between speed, distance, and time is easily remembered when you consider that speed is written in terms of units of distance per units of time. (miles per hour, or kilometers per hour, for example) Of course "per" means "divided by".

speed = distance/time

speed = (750 m)/(1/3 h) = 2250 m/h = 2.25 km/h

Logan's average speed is 2.25 kilometers per hou
