Homework Help: Physics

Posted by Tammy on Wednesday, September 12, 2007 at 4:36pm.

You are driving home on a weekend from school at 65mph for 130 miles. It then starts to snow and you slow to 45 mph. You arrive home after driving 4 hours. How far is your hometown from school?

First I found the time with d/v=t so 130/65= 2 hours

I used d= d_0 +vt
=130 +45(6)
=400 miles

I plugged in 6 hours for the time from adding 2 hours and 4 hours.
Is this correct?
