Question

In training for a swim meet, Logan swam 750 meters in 1.3 of a hour. His swimming partner , Mila swam 2.3 of Logan's distance in 1.4 of a hour. What is Logan's average swimming speed? What is Mila's average swimming speed? Compare Mila's and Logan's swimming speed.

Answer 1

Explanation:

For Logan:

Logan swam 750m

Logan distance = 750m

Time taken = 1.3×3600

Time taken = 4680

Logan average speed = distance/time

average speed = 750/4680

Logan Average speed = 0.160m/s

Mila swam 2.3 of Logan's distance

Milan distance = 1725m

Time taken = 1.4×3600

Time taken = 5040s

Milan average speed = distance/time

Milan average speed = 1725/5040

Milan average speed = 0.342m/s

Comparing Milan speed with Logan speed:

Difference in speed = 0.342-0.160

Difference in speed = 0.182m/s

This means that Milan speed is 0.182 greater than Logan speed.
