single transfer = 3MB/s
two transfer = 2MB/s x 2 = 4MB/s total
three transfer = 1.5MB/s x 3 = 4.5MB/s total
highest speed is three transfer simultaneously

since 90MB + 200MB + 300MB = 590MB > 577MB, all three flash drives are required.

90MB drive will fill up first after 90/1.5 = 60 seconds
total data transfer at 60 seconds = 60x4.5 = 270MB

transfer rate drops to 4MB/s with two drives. 200MB will fill up next after:
(200-60*1.5)/2=55 seconds
total data transfer in those 55 seconds = 55x4 = 220MB

data left=577-270-220= 87MB which will take another:
87/3= 29 seconds to finish transfer to the last 300MB drive.

Total time = 60 + 55 + 29 = 144 seconds
