It seems obvious, but you should always use the
equation:
average speed = ( total distance ) / ( total time )
Let = the one-way distance
Let = the total time

again:
average speed = ( total distance ) / ( total time )
average speed =
Divide through by
average speed =
average speed =
average speed =
average speed = mi/hr
