not possible. your lying obviously a 2 hour trip at roughly 65, cali you drive 75 plus reguardless in most areas, specially highways. but lets give you benefit of the doubt at 65 miles an hour. to cut your time in HALF (to 1 hour) you would have to go 130. doubling your miles per hour you tavel. to cut it to half an hour, you would have to go 162.5 mph. 250% of what you normally go, if the speed limit is 65 mph.
so pretty much
@65 you make it there in 2 hours
@130 you make it there in 1 hour
@162.5 you make it there in 30 minutes
this is the reason why speeding really does you no good. even going 90 in a 65 you don't cut off but maybe 15 minutes in a 2 hour trip.
