Is this your question?
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour. His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour. (the question is What is Mila's average swimming speed?)
Answer:
Mila's average swimming speed is 34.44 m/min.
Logan's average speed is 2.25 kilometers per hour.
Explanation:
Given:
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.
His swimming partner, Mila, swam 2/3 of Logan's
To Find:
What is Logan's average swimming Speed?
Solution:
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) "per" means "divided by".
![\left[Speed=(Distance)/(Time) \right]](https://img.qammunity.org/qa-images/2022/formulas/mathematics/high-school/t22iivzm4oivlmgn93ytlz.png)
![\left[speed = (750 m)/(1/3 h) = 2250 m/h = 2.25 km/h\right]](https://img.qammunity.org/qa-images/2022/formulas/mathematics/high-school/6vci4p132frluuhsv1dgwe.png)
Logan's average speed is 2.25 kilometers per hour.

Given:
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.
His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour
To find:
What is Mila's average swimming speed?
Solution:
The distance swam by Logan = 750 m
The distance swam by Mila = 2/3 of Logan's distance = 2/3 x 750 = 2 x 250 = 500
The time taken by Mila to swim 500 m = 1/4 of an hour = 1/4 x 60 = 15 Minutes [since 1 hr = 60 mins]
We know the formula as:
Now, substituting the values in the formula above to find the speed of swimming of Mila,
The average swimming speed of Mila =
Therefore, Mila's average swimming speed is → 34.44 m/min.
