Explain plan

Consider the following execution plan:

 -> Inner hash join (no condition)  (cost=366.50 rows=3600) (actual time=0.171..1.148 rows=3600 loops=1)
    -> Table scan on b  (cost=0.10 rows=60) (actual time=0.005..0.096 rows=60 loops=1)
    -> Hash
        -> Table scan on a  (cost=6.25 rows=60) (actual time=0.036..0.127 rows=60 loops=1)

Write down the time spent on executing the first row of the query.
