Question

Suppose you are driving to your vacation destination. You are driving at an average rate of 60 miles per hour. You must drive a total of 235 miles. If you have already driven 55 miles, how long will it take you to reach your destination? A. 4 hours B. 3 hours C. 2 hours D. 5 hours ered 10

Answer 1

If we must drive 235 miles in total, and we've already driven 55 miles, the distance to go would be:

$235-55=180\text{ miles}$

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,

$x=\frac{180}{60}\rightarrow x=3$

It would take us 3 hours to reach our destination

(Correct answer: Option B)
