d.Could all the NDAS offices transmit their invoices to Tampa between 5:00 P.M. and6:00 P.M. each evening? How would they achieve this goal? Look at the answer to Question 3 (the rightcolumn in the table in the answer for question 2). The sum of all the transmissiontimes in minutes per day (other than those from Tampa = 33100-3190 packages) is259.6354 minutes. That figure includes two transmissions for cities other than Tampa,one to a destination city and one to Tampa. Therefore, 259.6354/2 = 129.8177minutes to transmit to Tampa. Then, 129.8177/60 minute per hour = 2.163628 hours.Assuming there are no errors, it would take little over 2¼ hours for all the offices totransmit their invoices to Tampa with the current modem. However, using a 56 Kbpsmodem would decrease the time to (28800/57600)*2.16 hours or 0.5*2.16 = 1.08hours or 64.90885 minutes. This would nearly meet the goal. Therefore, you shouldrecommend obtaining 56 Kbps modems for all the offices.1.Would it be better to transmit all invoice information from the origin to Tampaand for Tampa to send the information to the destination?
