# Hot Air Balloon

### By: Christie and Sathvika

## Q1) What function relating the variables best describes this situation?

*f(x)=800-20x or d(t)=800-20t*

## Q3) How high was the balloon 5 min. before it was sighted? Show graph and explain.

900, because 5 min. before it was 800 ft, so plug in -5 in x. The answer would be 900

## Question #5

*d(t)=1200-20t*- 2nd balloon took 60 min. to land so 60-40= 20 min.
- 2nd balloon takes longer to land

## Question #6

*f(x)=800-30t*- 39-26.6=12.4 min
- It takes seconds faster for the third balloon to land.
