sql awr numbers not matching

Hi,

I am finding discrepancy between elapsed time value and timing in execution plan in .

values are mentioned below:-

Elapsed Time (ms)==> 9,398.95 ms (i.e., 9.3s)

but execution plan showing below:-

0 SELECT STATEMENT 97475 (100) 

1   SORT ORDER BY 377K 188M 226M 97475 (1) 00:19:30

2     TABLE ACCESS FULL F98865 377K 188M 55666 (1) 00:11:0

so, from execution plan, elapsed time should have been 19:30+11:00=30 minutes.

I believe both the values for samples execution over same time period, how can they be so different?
