Query for order/delivery turnaround time

Question

Hi, all-
I want to create a query that will show me the turnaround time from the time the sales order is posted to the time the delivery is posted. 
An additional twist:  we often have multiple deliveries on a sales order.  Would need to take all of these into account.
Is it as simple as querying the posting date and the Closed date?  But how would I do this?  Or do I need to somehow pull info from both the SO table and the delivery tables?
Thanks in advance,
Shelby

Shelby,
This is something like calculating Average Days to Pay where you need to find the avg turn around time in case of multiple deliveries for 1 Sales Order.
How do you plan to run this Report.  By entering a period range or by entering a Customer Code or by a Sales Order #
Use this query as an idea for the approach
SELECT DISTINCT T0.DocNum, SUM(DATEDIFF(DAY,T0.DocDate,T3.DocDate))/COUNT(T0.DocNum) AS [TurnAround Days],
COUNT(T0.DocNum) [Number of Deliveries]
FROM
[dbo].[ORDR] T0 INNER JOIN [dbo].[RDR1] T1 ON T0.DocEntry = T1.DocEntry
INNER JOIN [dbo].[DLN1] T2 ON T2.BaseEntry = T0.DocEntry
INNER JOIN [dbo].[ODLN] T3 ON T3.DocEntry = T2.DocEntry
WHERE T0.DocStatus = 'C'
GROUP BY T0.DocNum
Note:  This query will list all the Sales Orders that are closed and will show turnaround days to close the Order completely and the number of deliveries to close the order completely.
