Question

Jill swarm 400 meters in 4 minutes 42 seconds. If each lap is 50 meters long, which is most likely to be her time in seconds per lap?

Answer 1

To find Jill's average time per lap in seconds, we convert her total swim time to seconds (282 seconds) and divide it by the number of laps (8). Her average time per lap is 35.25 seconds.

Step-by-step explanation:

Jill swam 400 meters in 4 minutes 42 seconds, and we want to calculate her time in seconds per lap, with each lap being 50 meters long.

First, we convert her total time to seconds: 4 minutes is 240 seconds, plus 42 seconds gives us a total of 282 seconds for 400 meters. Since there are 8 laps in 400 meters,

we divide her total time by 8 to find her average time per lap.

282 seconds ÷ 8 laps = 35.25 seconds per lap

This is her average time per lap in seconds.
