Bernie's data transmission rate in Mbps

hi I need help with this assignment. It is for Computer networks Class. Please see attached file.

The assignment is on Ch1 and 2. This is the book link: h±ps://docs.google.com/fle/d/0B9NPPKc-w3zhWWE3X3k2LTZ2aUU/edit ( In your responses to quesTons 2, 3, and 4, you should write complete sentences and paragraphs. ) 1.

Bernie can travel at 8 km/hour. A. Determine Bernie's data transmission rate in Mbps (megabits per second, remember there are 8 bits/byte) iF he runs 7km. (Hint: determine how much data Bernie is carrying in megabits and how long it takes him to run 7km in seconds. Divide the amount oF data in megabits by the number oF seconds.) ANSWER: B. At what distance is Bernie's data rate equal to 100 Mbps? ANSWER: 1 University of North Florida
