Backed up assumptions Group 10

Assumptions: 1) Weight of a box would be around 5 lbs/ 2.5 Kg. This assumption is backed up by the citation from amazon "These things will weigh about 55 pounds each, but they’ll be able to deliver parcels that weigh up to five pounds. It turns out that the vast majority of the things we sell at Amazon weigh less than five pounds." link[1]

2) The maximum distance a delivery drone can cover is assumed to be 20 km on full battery. This assumption is based on our research in scientific articles in which most articles proposes maximum distances between 16 – 25 km on full battery.
