Narrative:

Assigned to cross 5 NM west lrp at 11000 ft. Captain was slow in descent. We were questioned as to descent rate for crossing traffic at 14000 ft. Captain picked up rate as we were again asked if we were 'out of 13000 ft.' I prompted captain 3 times. We were barely clear (1000 ft vertical) of traffic, but missed 5 NM west of lrp VORTAC by 1 1/2 mi. No further queries by ATC. I must be more forceful in my suggestion to the captain next time!
