You will need to swim 15 lengths and you will end up swimming 410 yards.
Some pools were built where the length is 25m or 25yards. So in a 400, there are 16 laps.
1/25 yards there, 25 back
4 lengths
In a standard yard pool, 25 yards, it takes 66 laps.
Yards.
440 divided by 25 = 17.6 so if you swum 18 lengths you would have swum 450 yards.
A regulation pool is 25 yards, so each lane is 25 yards long one way. That means you would go from one end of the pool to the other 40 times.
500 meters = 546.81 yards = 21.87 lengths of 25 yards each
in a swim meet a mile is considered 1650yds and that is 66 lengths. Actually 1650 meters ~ 1 mile, not 1650 yards. There are 5280 feet in a mile, and 3 feet in a yard. 5280/3 = 1760 yards per mile. 25 yards per length, then 1760/25 = 70.4 lengths per mile. So in a 25 meter pool 66 legths = 1 mile. In a 25 yard pool 70.4 lengths = 1 mile.
39 lengths of a 50m pool 20 lengths of a 25m pool 43 lengths of a 50yard pool 22 lengths of a 25yard pool
2500/20 = 125 lengths
Less than one, because one length in an Olympic pool is 50 meters.
One mile is 5,280 feet, or 1760 yards, or 1,609.344 meters
In a 25-yard pool, 40 lengths (or 20 laps) equals 1000 yards.
If each lap is 25 yards you must swim 70.4 laps to reach one mile.
