The average speed of this object between points C and D is:
.375 km/s
.375 m/s
2.67 km/s
2.67 m/s
The average speed between 4 and 16 minutes is:
5.2 km/s

.181 km/s
5.5 km/s
To calculate the average speed for the journey from A to C:
(distance A-B) + (distance B-C) divided by (time A-B + time B-C)
(distance 0-C) divided by (time 0-C)
(distance A-B x time A-B) + (distance B-C x time B-C) divided by (time A-B + time B-C)
(distance A-C) divided by (time A-C)

If a magician pulls a table cloth from under a table of dishes, the dishes stay in place. The reason for this:
Based on Newton's First Law, the dishes will stay in place due to inertia, the resistance to force.
