Hmm your chances sorry to say...
About zero, zilch, not gonna happen...
Every Honda motor, at least to my understanding, is an interference head. Meaning the valves will come in contact with the pistons if timing is lost aka you are screwed.
If you've already tried to turn the starter (don't try if you haven't yet) and hear a bad metal grinding sound then that's your answer. Also when was the last time you changed the belt, I never hear of them breaking at low power situations like on the highway? They usually go when you floor it, or slip a tooth when its cold.
At this point you're gonna have to put a new belt on it anyways which is really pretty easy once you already have the timing cover off and everything. Put a new belt on it, double check your timing marks, unplug the fuel pump (should be in the trunk), open your throttle, unplug the distributor, and check your compression. If you have no compression or can't get it to turn over then at least you already have the belt off. Cuz needless to say you're gonna have to rebuild the cylinder head. Also always replace the balance shaft belt too, if it goes it will slip the timing belt as I already found out on my old Eclipse.
For everyone out there who likes to press the limits this is why you replace your belts, change your oil, and do regular maintenance religiously. A $50 belt will save you hundreds not to mention a huge headache.
I should mention I don't know what engine and stuff you have, but on my 96 Accord EX 2.2 VTEC the engine is set up this way. As is every other car I've ever owned with a timing belt.

Like he said, the chances of survival are low. However I have seen Honda's make it through that. The easyest way to find out is to replace the belt and see if it still runs. A timing belt is easyer to R&R than a head.
90 Accords are fairly easy to do the job on. Have fun and cross them bones man.
