A 1.5 MB file is downloaded from the site in 27 seconds. How many minutes will it take to download an 80 MB file if the download speed increases by 20%?

1.5 MB and 80 MB are file sizes.

27 seconds – download time.

Downloads increased by 20%.

Let’s conventionally denote the download time of a file of 80 MB – x.

1.5 MB – 27 seconds.

80 MB – x seconds.

1.5 * x = 27 * 80.

1.5 * x = 2160.

x = 2160 / 1.5.

x = 1440.

1440 seconds download 80 MB file.

100 – 20 = 80.

80% downloads faster. according to the condition of the task, if the download speed increases by 20%.

1440 seconds – 100%.

x min – 80%.

1440 * 80 = x * 100.

115200 = x * 100.

x = 115200/100.

x = 1152.

1152/60 = 19.2.

A file of 80 MB will be downloaded in 19 minutes and 20 seconds.
