<PRE><B>Question 340344</B>
the overall average is really a weighted average
--
weighted average = total miles driven/total days driven = (212+104)/7=45.14
==
alternatively, you could figure the miles each day and multiply by the proportion represented by each day.
--
for example, day 1 miles=212, day 2 miles =104/6=17.33, day 3 miles=17.33 etc
each day represents 1/7 of the trip.
--
weighted average= 212*(1/7)+17.33*(1/7)+...17.33*(1/7)=212*(1/7)+17.33*(6/7)=45.14</PRE>
