Question

A cable modem downloads at 1200 kbps, kilobytes per second. How long will it take to download 9 megabytes if 6 megabytes is equal to 49,000 kilobytes? Round your answer to the nearest second.

Answer 1

Set up a ratio\[{9\over x}={6\over 49,000}\]\[x=73,500 \text{kbps}\]then divide by the rate of the modem\[\text{time}={73,500\text{kb}\over 1200\text{kbps}}=61.25s=61s\]Fairly sure I did that right

Answer 2

yes thank u so much
