Question
You are downloading a song. The percent y (in decimal form) of megabytes remaining to get downloaded in x seconds is given by y = – 0.1x + 1 after how many seconds the song will be downloaded completely?
Solution
When a song is downloaded completely the remaining percent is zero.
i.e y = 0
0 = – 0.1x + 1
0.1x = 1 second
x = `1/0.1 = 1/1 × 10`
x = 10 seconds
