Agent Bourne transferred classified files from the CIA mainframe into his flash drive. The drive had 3 6 . 5 36.536, point, 5 me
BaLLatris [955]
I'm not sure what the question is.

Given:
Flash drive capacity 1,000 megabytes
Initial content before transfer of files 36.5 megabytes

After 125 seconds, there were 549 megabytes on the drive.

549 - 36.5 = 512.5 megabytes is the weight of the transferred files.

512.50 megabytes / 125 seconds =  4.1 megabytes per second

The rate of transfer is 4.10 megabytes per second.

1000 - 549 = 451 megabytes free space.

451 megabytes / 4.1 megabytes per second = 110 seconds

It would take an additional 110 seconds to completely fill up the flash drive.

A shirt cant be in decimal so we remove the decimals, and take the as the answer. For the decimals, they are the remaining cloth.. to calculate the amount of remaining cloth we do:

1.860465116-1
