Question

A typical song downloaded from the internet is 4 megabytes in size. Lindy has satellite internet, and her computer downloads music at a rate of 256 kilobytes per second. If 1 megabyte equals 1024 kilobytes, about how many songs can lindy download in 2 hours?

Answer 1

so the first thing you do is you divide 1024 by 256. you will come out with the answer of 4. it takes 4 seconds to download 1 megabyte. but, it takes 4 megabytes, so you need to multiply 4 by 4. you will get 16. it takes 16 seconds to download 1 song. 

to figure out how many songs Lindy can download in 2 hours, you multiply 60 by 60. you will get an answer of 3600. there are 3,600 seconds in an hour. now to find out how many are in 2 hours you multiply 3,600 by 2. you will get a sum of 7,200

now to figure out how many songs Lindy can download in 2 hours, you divide 7,200 by 16. you will come out with a quotient of 450.

Lindy can download a total of 450 songs in the space of 2 hours.
