How many cu ft
if you swim 100m in 60 secs then you should be able to swim 100yd(=91.44m) in 60*91.44/100=54-55sec If you swim 100yd in 1 minute you probably will be able to swim 100m in 91.44/60*100=65-66 secs. Since 100m is longer than 100yd this time will be correct provided you can swim the last 10 meters at the same speed as you swim the 100yds.
