RIPv1 Summarisation

in CCNA & CCENT
Hi,
I was just wondering about summarisation.
If RIPv1 is summarising what happens to variable metrics?
If the router which is sending the summary knows of 2 networks which all are different hops away 1, 2.
172.30.1.0 172.30.2.0 192.168.1.0
Router
Router
Router2
Router 1
Boundary
What will he send to Router 1?
I guess he will summarise to 172.30.0.0 but what metric? 1 or 2?
Cheers
