Answer 1

You should be able to use something similar to the following:

select 
  cast(cast(avg(cast(CAST(times as datetime) as float)) as datetime) as time) AvgTime,
  cast(cast(sum(cast(CAST(times as datetime) as float)) as datetime) as time) TotalTime
from yourtable;

See SQL Fiddle with Demo.

This converts the times data to a datetime, then a float so you can get the avg/sum, then you convert the value back to a datetime and finally a time
