how much time is needed to distribute the file to all the theaters under ideal conditions?

Question

Suppose a movie studio wants to distribute a new movie as a digital file to 1,000 movie theaters across country using peer-to-peer file distribution. Assume that the studio and all the theaters have DSL connections with a 4 Mb/s upstream rate and that the file is 10 GB long. Approximately, how much time is needed to distribute the file to all the theaters under ideal conditions?

1000*Tt or just one Tt time??i think it should be just one Tt if we are sending to all the links at same time instant.

Comments

Here connection is peer to peer so no need to wait for any client.

Every studio to theatre is DSL.(separate connection)

So we can send at a  time.it is Tt only.

Approximately it takes 333.33 Minutes.
