Onf question that I am having trouble with is: One plane at 520 feet is ascending at a rate of 40 feet per minute, while another plane at 3800 feet is desending at a rate of 120 feet per minute. How long will it take the two planes to be at the same altitude?1 solutions Answer 422862 by Alan3354(30983)   on 2012-11-17 13:42:44 (Show Source): You can put this solution on YOUR website!One plane at 520 feet is ascending at a rate of 40 feet per minute, while another plane at 3800 feet is desending at a rate of 120 feet per minute. How long will it take the two planes to be at the same altitude? ========================= h(t) = 520 - 40t = 3800 - 120t 520 - 40t = 3800 - 120t 80t = 3280 t = 41 minutes --------------- but, the first plane will hit the ground in 13 minutes, the 2nd will impact at 31.67 minutes. So they'll be at the same altitude, zero, at 31.67 minutes.
