Remove duplicates from table

Could really do with you assistance here!

I have table test

test_id number(11) PK
test_name varchar2(100)
start_time date
end_time date

In essence I need remove the duplicate records from the table so that:

1|football|19/04/2009 17:15|19/04/2009 20:00
2|football|19/04/2009 17:15|19/04/2009 20:00
3|football|19/04/2009 17:15|19/04/2009 20:00
4|football|19/04/2009 17:15|19/04/2009 20:00
6|cricket|19/04/2009 13:15|19/04/2009 22:00
7|cricket|19/04/2009 13:15|19/04/2009 22:00
8|cricket|19/04/2009 13:15|19/04/2009 22:00
9|cricket|19/04/2009 13:15|19/04/2009 22:00

becomes;

1|football|19/04/2009 17:15|19/04/2009 20:00 6|cricket|19/04/2009 13:15|19/04/2009 22:00

Your help would truly appreciated with this one!

Thanks in advance,
