OH GOD THANK YOU JESUS! Thank you guys (gals?) So much! Onto the next question... :/

Ah crap. So 30=60t so 0.5=t So 120=x/0.5 -> 60= x And 60=x/(0.5+0.5) -> 60=x So is my total time = 1hr, drive time =0.5h With distance being 0.5h (120km/h) = 60km traveled?

Okay so we have 60=(120*t)/(t+0.5) 60 (t+0.5)=120*t 60t+30=120t 30=60? Not sure how to keep t since it would naturally cancel.

Okay so I think, but may be wrong, that Voverall should be 60.0km/h not 120km/h, so my equations would be (60.0km/h)(xh-0.5h)=(120km/h)(xh) and xh=(xh-0.5)+0.5h I am guessing that the substitution would be to put (xh-0.5h)+0.5h into the equation where xh is. Therefore...

I have changed the values, and the homework also changes every time I submit a response, I would just like to see an example worked out, so change the values as well if you want! 1. Homework Statement A person takes a trip heading south with an average velocity of magnitude 120.0 km/h except...
