Problema Solution
A plane flew from Airport A to Airport B at 900 m/h. It returned to Airport A at 800 m/h. The return trip took a half an hour longer than the outgoing trip. How far apart are the two airports and how long was the return trip?

900(x) = 800(30+x)
find x
900x = 800*30 + 800x
x= 240 minutes = 4 hours
