Hot Air Balloon
By: Sahithi Arimanda, Nikita Ganji
Problem 1
Our function is f(m)=800-20m .
Problem 4
It takes 39 minutes because you plug in 20 for y. 20=800-20m and we solved it and got 39.
Problem 5
The function is f(m)=1200-20m and it takes 20 more minutes to reach the ground for the second balloon. They both take 20 feet per minute.
Problem 6
The function is f(m)=800-30m and it would take 13 1/3 minutes less.This one descends 30 feet per minute while the others descend 20 feet per minute.
Problem 7
The function for the fourth balloon is 30m and to get the answer we did 30m=800-20m and m=16 minutes. At 16 minutes the first and fourth balloon are at 480 feet. That is the point of interception.
Problem 8
We did 0=800-20m and got m=40 minutes and then we plugged in 40 for m and did
800-20(40)=30(40) and we got 1200 feet. So they would have to start at 1200 feet.
