Displacement is the distance from the final placement of the object from the initial point. So, since the swimmer started and ended in the same spot, it is zero.
Well for a competitive swimmer in longcourse it should be about 4-6 ( depends on age an level) so the average person that doesn't practice swimming probably 15 minutes if they could even finish it( depending on how physically fit they are and how their general technique is in swimming) 400 meters is a lot for someone who doesn't swim- thats 16 laps in a shortcourse pool and 8 in a longcourse.
An olympic sized pool is 50 metres. If it is a 4x100 Relay one swimmer will swim 2 laps. If each swimmer does two laps and there is 4 of them, 8 laps will have been swum.
well the answer for this qustion depends on wether you're swimming long course or short course if you're swimming long course 200 yards would be 4 laps if you're swimming short course 200 yards would be 8 laps
about 10
Yes that's quite good. Most intermediate swimmers could manage a mile (70 laps) and so as a beginner 20 laps is a good start. I would recommend trying to increase by 4-6 laps each time you go to allow you to slowly build up your swimming.
It depends on what the lap is of. Running around a track? around a football field? swimming a lap in a pool?
On an outdoor track 4 laps equal one mile. In a swimming pool, a swimming mile is 33 laps down and back, a real mile is 36 laps down and back.
Less than half a mile, about .375 of a mile.
It is 2.5 laps/(3+6/60 minutes) = 2.5/3.1 =0.81 laps per minute, approx.
Two and a half laps
It depends on the size of the swimming pools. If the pool is small, you need to swim many laps to get to 1/4 mile. 1/4 mile is 440 yards.
im not really sure but, im a swimmer!
