Question

John swam 200 meters in 2 minutes 42 seconds. If each lap is 50 meters long, which is most likely to be his time, in seconds, per lap?.

Answer 1

Answer: 40.5 secs

Explanation:

1 minute = 60 sec

2 minutes 42 secs = 162 secs

So we know that 200 meters in 162 seconds

We know that 50 m is 1/4 of 200 Meters

So, we take 162 sec times 1/4 = 40.5 secs
