A file with a size of 7 MB is transferred after a while, the connection takes 28 seconds.

A file with a size of 7 MB is transferred after a while, the connection takes 28 seconds. Determine the size of the file (in KB) that can be transferred through another connection with a faster speed in 5 seconds.

To find the connection speed for the first case, you need to divide the file size by the time taken to transfer:

7 megabytes = 7168 kilobytes.

7168/28 = 256 kilobytes per second = 2 megabits per second.

If the speed in the second case is twice as high as in the first, then it is equal to 512 kilobytes per second = 4 megabits per second.

To find the size of a file that we can transfer in 5 seconds at a speed of 512 kilobytes per second, we need to calculate the product of these values:

512 * 5 = 2560 kilobytes = 2.5 megabytes.
