It depends in the standard of the simming race, for Olympic or World Championships then the pool has to have 10 lanes however only the middle 8 are used.
For lesser competitions it depends on how many lanes the pool has, usually a minimum of 6 however for smaller and older pools which are very rarely used there may be 4 or 5 lanes
it depends on how long it is....but if its 8ft or more that's a lap
There are 10 lanes in an olympic swimming pool
There are 1,609.344 meters in a mile. When 1 length = 1 lap, you would need to complete 64.3 laps to swim a mile.
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.
1 mile is equal to 4 laps of a standard 1/4 mile track.
It depends on how big the laps are.
Assuming laps means two lengths (there and back in a lane): 1yd = 0.9144m 20yd = 18.288m 2 lengths = 36.576m 1km = 1000m = 1000m / 36.576m ~= 27.34 laps (just over 54 2/3 lengths)
1 mile/0.8 mile = 1.25 laps.
72 laps make a mile. so calculating the fraction 18 laps would be 1/4 of a mile!!!!
A mile in a 25 yard pool equals 71 lengths or 36 laps (1,760 yards in a mile). A mile in a 25 meter pool equals 66 lengths or 33 laps (1,650 meters in a mile). In a 50 Meter pool, a mile is 1,650 meters, which is 33 lengths or 17 laps of the pool. 2 lengths of a pool equals 1 lap.
8 laps = 1 mile
assuming a 25mx10m pool, each lap = 70m 1 mile = approximately 1609 metres 50 mils = 80,450 metres 80,000 / 70 = 1149 laps
