So, if two objects approach each other at 60mph, they are actually travelling at 119.9994mph relative to each other?

- donkeyd 11y agoI'd like to say 'No' from intuition, but it is probably flawed.
- marcosdumay 11y agoAre you sure you didn't mean a few (about 10) nines somewhere?
- learnstats2 11y agoah, in fact I did! I forgot to square c :)
- mavdi 11y agoNo, much closer to 120. 120 / (1 + (60 / 670616629) * (60 / 670616629)) ~= 119.9999999999990394
- snowwrestler 11y agoThe difference between this speed and 120 mph is less than half a picometer per a second, which illustrates why we don't typically notice relativistic effects at highway speeds. :-)
