Question

GAS MILEAGE

 

A car magazine is trying to write an article that rates the top 5 most fuel efficient SUVs (the SUVs that can drive the most miles for each gallon of gasoline). They make sure each model of SUV has exactly 10 gallons of gasoline in its fuel tank and reset the odometer (instrument that measures the distance a vehicle has traveled) to zero. The SUVs are then driven until they run out of gasoline. The distance on the odometer is recorded.
A. Independent variable(s):_______________________________________________________________
B. Dependent variable: _________________________________________________________________
List 3 variables that should be controlled (held constant

Answer 1

Mileage Experiment:
 
The independent variable is the model of SUV.
 
The dependent variable is the distance each SUV gets on 10 gallons of gas.
 
Some controlled variables would be road conditions, weather conditions, and type of terrain (country vs. city, hilly vs. flat).
 
There is no control group for this experiment.
