A plane going 300 miles per hour is going 440 feet per second. (300 * 5280 / 60 / 60) In four hours, it will have traveled 1,200 miles, or 6,336,000 feet.
3 hours and 30 minutes = 3*60+30 = 210 minutes The planes is therefore going 1000/210 = 4.761904761904762 miles in a minute This means that the plane is going at a speed of 4.761904761904762*60 = 285.7142857142857 miles an hour.
900/2.5 = 360 miles per hour
