Answer:
after 7 minutes
19,600 feet
Step-by-step explanation:
Here's the "pencil and paper" solution:
The two altitude equations are ...
y = 41300 -3100x
y = 2800x
They can be solved by setting the expressions for y equal to each other.
2800x = 41300 -3100x
5900x = 41300
x = 41300/5900 = 7
y = 2800·7 = 19600
The planes will both be at 19,600 feet after 7 minutes.
add them together then divide by 5
81 +86 +81 +76 +71 = 395
395/5 = 79
your average was 79
Would it be 9 because 8 times 3 equals 24 and 3 times 3 equals 9
