Carlson city and mason city are 15 miles apart. if you leave carlson city and drive at 45 miles per hour, how long does it take you to reach mason city?
Using the formula for distance-speed and time, i, e, [tex]s=v*t[/tex], we can find the answer. Since s=15 miles, v=45 mph, then t=s/v=15/45 hours=1/3 hours=20 minutes.
