A 9MB file is transferred over a connection in 240 seconds. Determine the size of the file (in MB) that can be transferred over the same connection in 80 seconds.
Let’s make the proportion:
9 MB – 240 seconds
x MB – 80 seconds
240x = 9 * 80
(unknown in one direction, known in the other)
x = 9 * 80/240
x = 720/240
x = 3
Answer: 3
