A 2MB file is transferred over a connection in 64 seconds. Determine the file size (in KB)

A 2MB file is transferred over a connection in 64 seconds. Determine the file size (in KB) that can be transferred over another connection at twice the speed in 40 seconds.

First, let’s convert the specified file size from MB to KB.

Since 1 MB contains 1024 KB, we get:

2 * 1024 = 2048 KB.

Determine the transfer rate of this file.

We divide its size by the transmission time, which is 64 seconds.

Will be:

2048/64 = 32 KB / s.

From this it follows that the doubled transmission rate will be equal to:

32 * 2 = 64 KB / s.

Thus, the size of the file that will be transferred in 40 seconds will be:

64 * 40 = 2560 KB.

In MB we get:

2560/1024 = 2.5 MB.

Answer: 2560 KB.
