This means that the battery is discharged down to 10.5 volts over a 20 hour period while the total actual amp-hours that it supplies are measured. Sometimes ratings at the 6 hour rate and 100 hour rate are also given for comparison and for different applications.
Pool meets are usually no more than 4 hours, but beach meets last about 7 hours. It depends how many events are in the meet. And then if it is a really big meet (like a tournament kind of) it can last days. Hope that helps.
Interval Basics. Swim times vary according to age and ability. In general, average lap swimmers in a 100 m pool comfortably complete a 100 m swim in two minutes. A swimmer who has an easy interval time of two minutes would consider a 100 m time of one minute 30 seconds very good.maller pools yield faster times because you can push off hard from the wall, and typically swim faster under water before surfacing. Olympic pools measure 50 m, so for a 100 m swim, you make one turn to complete the distance.
