# Hot-Air Balloon

### By:Pranitha and Shradha, Period 5

## Question 1

The function that relates it the variables is F(x)= 800-20x

## Question 4

The balloon will reach an altitude of 20 feet at 39 minutes and an will land at 40 minutes. It will land in 40 minutes because 800 divided by 20 is 40 and it will reach an altitude of 20 feet at 39 minutes because the balloon travels at a rate of 20 feet per minute so it will be a minute before it lands.

## Question 5

The function it represent the second balloon is f(x)= 1200-20x and the descent is longer than the first balloon because it takes 20 more minutes for the second balloon to land. The relationship between the two lines is that the second balloons line is not as the first balloons line since the second balloons descent is slower.
