    The closing speed of the two planes = 200 + 250 = 450 mph The combined distance traveled by the planes is 1800 miles before they pass each other is 1800 miles. Therefore the elapsed time before the planes pass is given by 1800/450 hours. Now after calculating the elapsed time you need to add it to 11 AM.
