Full Answer. The instantaneous speed of an object should not be confused with the average speed. For example, a person who drives 60 miles in a single hour has an average speed of 60 miles per hour, but the instantaneous speed of the vehicle could vary greatly from one instant to another.
If the velocity is 10 m/s for 10 secs and 0 for another 10 secs, then the average is 5 m/s which is non-zero over the 20 second period. But the instantaneous vâ¦elocity is zero for the period from 10 to 20 seconds.
