David swims the 100-meter freestyle in 48 seconds.  He swims the 100-meter backstroke 4 seconds slower than he swims the 100-meter freestyle, he swims the 100-meter butterfly 3 seconds slower than he swims the 100-meter backstroke, and he swims the 100-meter breaststroke 2 seconds slower than he swims the 100-meter butterfly.  What is the combined length of time, in seconds, it would take for him to swim all four 100-meter events (the freestyle, the backstroke, the butterfly, and the breaststroke)? Let's think step by step and output the final answer after "####".

David swims the 100m backstroke at 48+4=52 seconds.
He swims the 100m butterfly at 52+3=55 seconds.
He swims the 100m breaststroke at 55+2=57 seconds
IN total, it would take David 48+52+55+57=<<48+52+55+57=212>>212 seconds
