(1) Zipline has a Distribution Center (DC) in the country of Calafia with 2 Zips (drones), Zip-22 and Zip-24. Zipline services 5 hospitals in Calafia, each one at a varying distance away from the DC. The distances are as follows: Hospital A: 10km Hospital B: 20km Hospital C: 30km Hospital D: 40km Hospital E: 50km. Each Zip takes off from the DC, flies at a constant speed of 60km/h, drops the package via parachute and returns back to the DC. Assume turnaround time is instantaneous. Scenario: Hospitals A, B,C, D, & E all coincidentally have emergency cases of malaria and each hospital needs exactly 2 units of blood each (2 units = 1 package). What is the fastest time Zipline Calafia could fulfill these 5 orders? Please provide the time and the delivery schedule for each Zip.
