A student wrote software that controls a drone. In this software, East is positive î direction, North is positive y direction, and up is positive 2 direction. For each movement, the student inputs the directions as such: (A i , B j, C z), where A, B, and C are meters to travel. The drone flies in that direction in a straight line, and records how much time it took. Each new motion is relative to the present position. Meaning, a motion of ( 5i,0j, 0k ) followed by ( 5i,0j,0k) moves a distance of 10m. The following inputs were given, with their corresponding times in flight: (-4.2 î, 4.2 j, 1.4 2) -- 2s (16.1 i, -11.4 j, -18 2) --- 7.4s (22.8 i, 25.5 j, -21 2) --- 10.85 What was the average speed during the entire flight?
