On a road, a solid line divides lanes of traffic which are going in opposite directions. A line composed of dashes divides lanes of traffic going in the same direction.
It depends on the pool. Most competitive swim meets take place in 8-lane or 10-lane pools. Meets taking place in 10-lane pools typically fill the entire pool for the preliminary heats. In other words, all 10 lanes are taken up by swimmers. However, in the semi-finals and finals, only 8 lanes are used. This keeps the two outside lanes empty. However, meets can take place in pools of any size. There can be 6-lane pools or 4-lane pools. It is not always the same.
Well, the lanes are for people who want to do lengths (lengths of the pool). :)
There are many different kinds. The most common is 6 lanes. There are also a lot of 8 lane pools.
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
How do they not? They have alot like using math to make sure the lanes in the pools are the exact same
Either 25 yards or 25 meters. There are even some pools that are 50 meters. But usually the pools are 25 yards.
A real life example of a segment bisector is a median of a road. A median is the physical barrier that divides two lanes of traffic heading in opposite directions. The median bisects the road meaning it divides the road into two equal parts. It is the perpendicular bisector of the segment formed by the two lanes of traffic.
Competitive swimming pools widely vary in width. The width (in feet) changes depending on how many lanes it has. Most competitive pools have either six, eight, or ten lanes. An official Olympic sized swimming pool is 50 meters by 25 meters. It is ten lanes wide.
As far as I know, regulation dimensions for a short course pool is 8 lanes wide by 25 yards long. Long course pools are 8 lanes wide by 50 meters long. However, I have seen a lot of competitions in 6-lane pools, and some in 10- or 12-lane pools. One time, I went to a swim meet in a 4-lane, 20-yard pool, but that was pushing the limit.
FINA which is the world governing body for international swimming calls for a 50 Meter pool with 8 lanes. However movement is being created for having pools built with 10 lanes, with the outer 2 not being used for competition. (The waves created by swimmers bounces off the side walls and 'slows' down the swimmers in those lanes, thus an buffer is created by not using lanes 1 and 10 in competition). That said, if you are talking about size, Olympic generally refers to the length of the pool, not the number of lanes.
This can vary greatly with the width of the lanes. Often Olympic sized pools are about 50 meters long by 25 yards wide.
