After some connection at a speed of 5120 bits per second for 24 seconds, a file is transmitted.

After some connection at a speed of 5120 bits per second for 24 seconds, a file is transmitted. Determine the connection speed (in bits per second) through which the same file will be transferred for 15 seconds.

Option number 1.

Let’s find out what the size of the file will be equal to, which is transmitted through the connection at a speed of 5120 bps:

5120 * 24 = 122880.

Let’s determine what the connection speed will be if it takes 15 seconds to transfer it:

122880: 15 = 8192.

Answer: 8192.

Option number 2.

Let’s determine how many times the time period is 15 seconds less than the time period 24 seconds:

24: 15 = 1.6.

Let’s determine what the speed of the second connection will equal in this case:

5120 * 1.6 = 8192.

Answer: 8192.
