Suppose you are driving to visit a friend who lives far way. You are driving at an average rate of 55 miles per hour. You must drive a total of 295 miles. If you've already driven 20 miles, how long will it take to reach your destination?
B. 5 hours, because you need to drive 295 miles but you already drove 20 miles so you subtract 295 minus 20 which gives you 275. So then, you divide 275 by 55 since you drive 55 miles per hour which gives you 5 hours.
