The formula for the size of a file that was downloaded over time t and at an average rate r is r. t. Siena downloaded a file at a rate of 800 kilobytes per second for about 110 seconds.
What calculation will give us the estimated size of the file Siena downloaded, in megabytes?

The size of file downloaded is  88 megabytes.

Step-by-step explanation:

Given that:

Average rate of downloading the file =

Time taken to download =

Formula for the size of file downloaded =

Rate of downloading,

Time taken, = 110 seconds

To find:

Size of file downloaded in megabytes = ?

Solution:

First of all, let us apply the given formula to find the size of file downloaded:

Size of file downloaded =

Size of file downloaded = 800 kilobytes seconds 110 seconds =

88000 kilobytes.

Now, let us convert the unit kilobytes to megabytes to find the answer.

Conversion formula:

1000 kilobytes = 1 megabyte

Let us use unitary method to find the number of megabytes in 88000 kilobytes.

1 kilobytes = megabytes

88000 kilobytes = 88000 megabytes

88 megabytes.

Therefore, the size of file downloaded is  88 megabytes.
