Flights 104 and 217 are both approaching O Hare Internationa

Flights 104 and 217 are both approaching O\' Hare International Airport from direction directly opposite one another and at an altitude of 2.5 miles

Solution

Distance between the tower and flight 104 = tan 17 degree 47 minutes / 2.5 = 0.321/2.5 = 0.1284 miles

Distance between the tower and flight 217 = tan 12 degree 39 minutes / 2.5 = 0.224/2.5 = 0.0896 miles

Therefore, total distance between planes = 0.1284 + 0.0896 = 0.218 miles
