heres one for you.
3 people go for a swim.
they all start from the same point, swim around the same course, in the same direction although at different speeds.
swimmer 1 is the fastest and completes 3 laps of the 500m course in 36 mins
swimmer 2 completes 3 laps of the 500m course in 38 mins
swimmer 3 completes the 3 laps of the 500m course in 44 mins.
At one point swimmers 1 and 2 lap swimmer number 3.
Question 1: is this possible based on the recorded times?
Queston 2: if not, what other sceanrios are there?
1.no
is this a trick question? it possible to swim that slowly??
Of course it is possible.
Would mean some very funny splits ( individual lap times ) though.

answer to q 1 - yes, it is possible, but swimmer 3 would have to unlap themselves before the finish of the swim.
doesn't say they all start together, or swim at constant speeds
if no one was unlapped (and they werent), could it be assumed that perhaps swimmer 3 did in fact only complete 2 laps??!!
swim was open water in suits. daft choppy, zero visability and 150 other people in the drink at the same time!
As Swimmer 3 was only 2.6 minutes a lap slower than swimmer 1, given constant speeds it is not possible.
Q2 - Treadmill.
b: They all lap one another at the same time, slit the arses of their wetsuits, bum one another in human chain stylie and find the cycle very difficult.
So does this mean you are wondering why someone who swam slower than you finished ahead of you in a recent tri?
As has been said above, if the swimmers all started at the same time and form the same place then there is no way with those times that swimmers 1 and 2 would have lapped swimmer 3 unless swimmer 3 only did 2 laps.
I think that what bikingcatastrophe said is true - swimmer 3 only did two laps in which case they were lapped prior to finishing their second lap...
then my mates is a cheeky ****er! (as expected!)
Happened to me once in a Cx race.
I was the one being lapped.
One of my best results.
My head teacher once completed the London Marathon in under three hours and was hugely pleased with himself (and proceeded to tell the school in assembly).
It turned out he had 'got lost' and taken a short-cut and later was disqualified.
Cock.
i think it's possible, swimmer three needs to be very slow in first lap then speeds up dramaticaly. i think he'd have to be a pretty strong swimmer though.
A pretty strong swimmer to do 500m in 44 minutes? Isn't that more 'controlled drowning' than swimming?
I read it as 500m laps so 1500m in 44 minutes
Oh yes, you're right. 44 minutes is still not quick!
I read it as 500m total - hence my comment above... guess you could take it either way!
if you take it as 3 500 m laps basically he would have to do the last lap in less than 6 minutes in order that the other two could have finished before he started it and not been relapped,so that would make him a pretty strong swimmer. if it's a total of 500m then yes they are all simultaneously drowning and anything is possible.
