I = PRT

1800 = P * 0.05 * 9

1800 = 0.45P

1800/0.45 = P

4,000 = P

A small airplane flies from Big Lake to Pine City every day, with a 30-minute layover in Summerville. The distance between Big Lake and Summerville is 675 miles, and the distance between Summerville and Pine City is 625 miles. If the airplane flies at an average speed of 200 mph, how long does the whole trip (including any stops) from Big Lake to Pine City take?

675 + 625 = 1300 miles

1300 / 200 = 6.5 hours

6.5 + 0.5 = ?
