Answer:
Logan's average swimming speed = 0.625 metres/second
Mia's average swimming speed0.833 metres/second
Explanation:
Speed is obtained by dividing the distance covered by the time taken to cover such a distance.
It will be necessary to make sure we are working in seconds for our time units.
Logan's swimming time: 1/3 hours will be = 20 minutes = 1200 seconds
Mia's swimming time: 1/4 hours will be = 15 minutes = 900 seconds
Logan swam 750 metres. Logan's swimming speed will be
750metres / 1200 seconds = 0.625 metres/second
Mia's distance swam is 3/3 of Logan's. If we reduce the fraction 3/3 to its lowest term, we will have that it will be = 1/1.
1/1 X 750metres = 750 metres.
This means that Mia swam exactly the same distance as Logan.
Mia's swimming speed = 750 metres/ 900 seconds = 0.833 metres/second
