If we must drive 235 miles in total, and we've already driven 55 miles, the distance to go would be:
[tex]235-55=180\text{ miles}[/tex]Now, we know we're traveling at a constant rate of 60 miles per hour. (60 miles every hour) let's use this and a rule of three to know how long will it take us to reach our destination:
Thereby,
[tex]x=\frac{180}{60}\rightarrow x=3[/tex]It would take us 3 hours to reach our destination
(Correct answer: Option B)
