A car drives from point A to point B at 30 mph. The car then drives from point B to point A at 60mph and saves 1/4 the amount of time. How far did the car drive total.
I can't figure this out for the life of me. I would greatly appreciate some help.
Thanks!
Edit: My teacher says this will be on the exam. I think it's a trick question since he has doubled his speed and is therefore saving 1/2 his time if he is driving the same distance at twice the speed.
