Question

in training for a swim meet Logan swim 750 m in 1/3 of an hour. His swimming partner Mila swim 2/3 of Logan's distance and in 1/4 of an hour. What is Logan's average swimming speed?

Answer 1

Average speed

The average speed can be computed as the ratio of the distance over the time take to cover that distance. Being d the distance and t the time, we have:

`v=(d)/(t)`

Logan swims 750 m in 1/3 of an hour. Let's work in meters and in minutes to make calculations easier. The time taken by Logan is 1/3 of an hour. Since one hour has 60 minutes:

t = 1/3*60 = 20 minutes

The distance is 750 m. Let's calculate the average speed

`v=\frac{750\text{ m}}{20\text{ min}}=37.5\text{ m/min}`

Logan's average swimming speed is 37.5 m/min
