Assume a red plane leaves from city A to city B and at the same time a blue plane leaves from city B heading towards city A. The wind current is around 5mph and is travelling against the blue plane. Both planes are travelling at 120mph relative to the wind (not the ground). If the distance between the two cities is 300 miles, after how long will the two planes meet?
