Hello, &amp;nbsp;the correct term for it is &amp;nbsp;&quot; average rate of change &quot;.


Your term &amp;nbsp;&quot; average rate of speed &quot; &amp;nbsp;is &amp;nbsp;INCORRECT. 


&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;Such collection of words is &amp;nbsp;&amp;nbsp;NEVER &amp;nbsp;&amp;nbsp;USED.



Be careful with terminology : when you use it incorrectly (even one incorrect term), it just says a lot about you . . .
