The time taken by a factory line to move 8. 5 m along the line is 38.636sec
Speed is different from velocity, It is same when your distance and displacement is equal.
Displacement is equal to shortest path between two points where distance is defined as the total length of path between two points.
Similarly, speed is defined rate of change of distance, whereas velocity is defined as rate of change of displacement.
Since, we have speed by which parts of automobile is moving also, we also have distance to which we need to move parts.
So, we can apply distance-speed formula
We know distance=speed × time
=>8.5 = 0.22×t
=>t=8.5/0.22
=>t=38.636sec.
Hence, total time required to move parts of automobile is 38.636sec.
