Ellen is downloading a file. after 2 minutes, there are 38.4 megabytes left to download. after 8 minutes, there is only 9.6 megabytes left to download. what is the size, in megabytes, of the file.?

The size of the file is of 48 megabytes.

Step-by-step explanation:

8-2 = 6 minutes

38.4 - 9.6 = 28.8 megabytes

As we can see, 28.8 megabytes were downloaded in 6 minutes. Assuming a constanct and non stopped download speed, we can affirm that 4.8 megabytes were download per minute (28.8 / 6 = 4.8). As after 2 minutes, there were 38.4 megabytes left, in order to know the size of the file we have to do the following calculation:

38.4 + (4.8 x 2) = Size of the file

38.4 + 9.6 = 48 megabytes

The size of the file is of 48 megabytes.
