Acertain compact disc (cd) contains 783.216 megabytes of digital information. each byte consists of exactly 8 bits. when played, a cd player reads the cd's information at a constant rate of 1.1 megabits per second. how many minutes does it take the player to read the entire cd?

Time takes the player to read the entire CD is 94.9 minutes.

Explanation:

compact disc (CD) contains 783.216 megabytes of digital information.

Each byte consists of exactly 8 bits.

constant rate of 1.1 megabits per second

How many minutes does it take the player to read the entire CD?

1 Megabites = 1000000 bites

783.216 megabytes = 783216000 bites = 783216000 x 8 = 6265728000 bits

1.1 megabits/s = 1100000 bits/s

thus

t =  6265728000 bits/1100000 bits/s

 = 5696 s

 = 94.9 min
