320 meters
The average speed is 5 metres per second.
Speed = distance/time So speed = 100/5 = 20 Answer: 20m/s.
If an object is travelling 100 meters in 1400 seconds, then it is travelling (100 / 1400) or about 0.0714 meters per second.

Change of speed divided by time gives you average acceleration. For example, a change of 30 m/s during 5 seconds gives you 6 meters per second square - this is the average acceleration during those 5 seconds. If acceleration is constant, then this is also the acceleration at any moment during those 5 seconds. For more complicated functions (non-constant acceleration), derivates (a topic in calculus) has to be used. Specifically, the acceleration is the derivative of the velocity.
If an object moves 50 meters in 5 seconds, its average speed is 50/5 = 10 meters per second.
The average speed is 5 metres per second.

To get average speed, just divide distance by time. In this case, you divide whatever distance an object moves during the 11 seconds, by the 11 seconds.
During the 5 seconds, gravity adds 5G = (5 x 9.78) = 48.9 meters/sec to the object's downward speed.During that time, it's average downward speed is 1/2 of [ Vi + (Vi + 48.9) ] = Vi + 24.45 m/s.In 5 seconds it falls 5(Vi + 24.45) = 5Vi + 122.25 meters.5Vi + 122.25 = 240 meters5Vi = 240 - 122.25 = 117.75 metersVi = 117.75 / 5 = 23.55 meters per sec.
To determine average speed, you need to know what distance the object traveled in meters over how long it took the object to travel that distance in seconds.
Th eobject traveled 82 meters in 42 seconds, so average speed is 82/42 = m/s = 1.95 m/s

30 meters subtends 100 seconds of arc.I get a distance of 61,879 meters.
Ignoring air resistance, it would be 706 meters .
