Any help will be appreciated

Scenario: You are a networking and communications consultant working for HoustonComm Services, Inc, further referred to as HCS. HCS is a company providing technology consulting services to start-ups and established large companies. Recently HCS has been approached by Mr. Smith, the Chief Operations Officer of Procter & Gamble (PG). PG has many regional divisions across US, each organized around a central regional headquarter. They are now trying to expand into the South US area and are working on the logistics for opening a new regional headquarter just south of Dallas. As part of these efforts, Mr. Smith has recently contacted HCS to provide them with one consultant to help with few communications-oriented tasks. You are assigned to this role. 

Available information as provided by PG: The communications architecture for the new regional headquarter has been established already. The new location south of Dallas will include a 3-story office building and a very large warehouse in close proximity to the office building. 

Task 1: It has been established that communication between a supervisor's computer and a computer that controls equipment within the warehouse will use an encoding of 8 bits per symbol. What is the baud rate if the bit rate of the communication line is 1,024,000 bps? 

Task 2: It is known that the established architecture includes a direct wired voice communication option between supervisors and workers (using voice terminals at set locations) in the warehouse. For that part, the communication has a wavelength of 0.4 meters and a speed of 4x106 meters per second. What is the frequency of this communication?
