I need this by 9 am est tomorrow.  Show all work thanks.

Consider that the storage capacity of a single-sided, single-layer
DVD-Video disc is approximately 4.7 GB (4.7 billion bytes). Using a
bit rate of 56 kbps for a high speed telephone modem connection, how
long would it take to download this amount of data? If it takes you 10
minutes, roundtrip, to drive to the local video store, rent a DVD and
bring it home, what is the bit rate of your car in this particular
application?

((4,700,000,000 / (56,000/8))/60)/60
= 186.507937 hours to download a dvd not accounting for connection
overhead and assuming it performs at the rated maximum speed.

4700000000*6 = 28200000000 B/hr

((28200000000/60)/60)*8 = 62.6666667 Mbps
