How many minutes does Ray take to swim a mile in cold water? ** Cold water mile = <<16=16>>16 minutes
How many minutes does Ray take to swim a mile in warm water? ** Warm water mile = 2+2(16)=34 minutes
How many minutes does Ray take to swim 3 miles in cold water? ** 3 miles in cold water: 3(16)=<<3*16=48>>48 minutes
How many minutes does Ray take to swim 3 miles in warm water? ** 3 miles in warm water: 3(34)=<<3*34=102>>102 minutes
How much longer does Ray take to swim 3 miles on a hot day than a cold day? ** Ray takes 102-48=<<102-48=54>>54 minutes longer
