one plane at 520 feet is ascending at a rate of 40 feet per minute while another plane at 3800 feet is descending at a rate of 120 feet per minute how long will it take the two planes to be at the same altitude
Answer provided by our tutors
Let 't' represent the time (in minutes) that the planes need to reach the same altitude.
520 + 40t = 3800 - 120t
