Join And Sum Query

how do I add in a 3rd and 4 table to the mix and get their sums and group by ...The top select works fine the lower one is what I was thinking is this.....

Select Distinct
P.CustID, P.Acct, P.Title, P.FirstName, P.LastName,
A.Trips, A.MoneySpent, A.Bal
FROM dbo.Cust P
INNER JOIN
(SELECT
CustID, Sum(Days) as Trips, SUM(MoneySpent) as MoneySpent,
Sum(Balance) as Bal
FROM dbo.CAsh
Where Accumulator='DP'
GROUP BY CustID) A ON P.CustID = A.CustID

The 2 new tables are ViewDis (X) - Sum (Distance)and ViewACC (Y) Sum Fields required Hours, Min, (Group by) Building and Date.

Select Distinct
P.CustID, P.Acct, P.Title, P.FirstName, P.LastName,
A.Trips, A.MoneySpent, A.Bal, X.Distance, Y.Hours, Y.Min, Y.Building
FROM dbo.Cust P
INNER JOIN
