One minute after take off, an airplane altitude was 4,000 feet. three minutes later , it was 20,000 feet what was the planes average altitude change , in feet per minute, during those three minutes

The average altitude change of plane with time is 8,000 feet per min .

Step-by-step explanation:

Given as :

The initial height of plane after 1 min take off = 4,000 feet

The final height of plane after 3 min later = 20,000 feet

Let The rate of change of altitude in feet per min = s feet per min

Now, According to question

The change in altitude = final altitude - initial altitude

Or, D = 20,000 feet - 4,000 feet

I.e Distance change = 16,000 feet

The change in time = final time - initial time

Or T = 3 min - 1 min

I.e Time change = 2 min

Speed =

So, s = feet per min

∴    s = 8,000 feet per min

So, Rate of change of altitude with respect to time = s = 8,000 feet per min

Hence The average altitude change of plane with time is 8,000 feet per min . Answer

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

if you need , reply with more info. u.
