Solution: In 7.13 seconds, moving .0004230 meters in each of them, an object would move ( 7.13)( .0004230) meters, or .003015 meters.
Generalized Response: In time interval `dt sec, moving at speed v measured in meters/second, the distance is `dist = v `dt.

Figure description:
The figure below depicts the fact that if we know vAve and `dt, we can find `ds. The relationship between vAve, `dt and `ds is indicated in red.
In this figure vAve stands for velocity, which is just like speed except that it also has a direction. For example a velocity can be positive or negative. The quantity `ds is called displacement and is just like distance except that it has a direction, just like velocity. For example, displacement can be positive or negative.
