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?

You covered 130 miles in the first two hours (130/65 = 2). You then traveled 45 mph for 2 hours, so you went 90 miles (45*2).
130 + 90 = 220 miles
