Question

An mp3 takes up about 16 kilobytes of memory per second of music. if you owned a one terabyte hard drive and filled it with only mp3s, how many days' worth of music would you have? (keep track of units: kilobytes to terabytes and seconds to days)

Answer 1

60 sec. = 1 min. 3,600 sec = 1 hr. (60 sec x 60 minutes) 86,400 sec= 24 hr. (3,600 x 24) Given : 16,000 (bytes per seconds, for mp3 ) 86,400 X 16,000 = 1,382,400,000 bytes for 24 hrs. 1,382,400,000 = 1,382.4 mega bytes (Mb.) for 24 hrs of music Looking for how many days are in 1,000,000 Mb. 1,000,000 / 1,382.4 = 723.379629 Days worth of music.
