Question

Travis observes a decrease of 20 seconds for each additional megabyte downloaded in a file. If there were 115 seconds remaining when he started the download, what is the constant rate of change (k)?

a) 20 seconds

b) 15 seconds

c) 10 seconds

d) 5 seconds

Answer 1

The constant rate of change (k) in the context of the download time decreasing by 20 seconds for each additional megabyte is 20 seconds per megabyte.

Step-by-step explanation:

The question asks about the constant rate of change (k) in the context of a download time decreasing situation. Travis observes a decrease of 20 seconds for each additional megabyte downloaded. Since there were 115 seconds remaining when he started the download, the constant rate of change is the amount by which the download time decreases per megabyte, which is simply given as 20 seconds per megabyte in this context. Therefore, the constant rate of change is 20 seconds.
