A weather research airplane began descending from an altitude of 36000 feet above its base at a rate of 125 feet per minute how long did it take for the plan to land at its base
Okay, basically, this problem is asking you to divide 36000 by 125 to get the number of minutes it takes.
36000/125=288
So, you could just say 288 minutes as your answer, but, let's put it in hours to be more realistic. There are 60 minutes in an hour, so let's divide it by 60.
288/60=4.8
.8 is equal to 48 minutes
So, 4 hours and 48 minutes is your answer, or 288 minutes!
