A racecar is equipped with a computer that records the reading on its speedometer every second during a race. If you graph this data, what will be the best choice for the dependent variable?
a. time
b. position
c. average velocity
d. instantaneous velocity
Because it records speed of the car at a certain time, the independent variable should be time and dependent would be speed or velocity. Since it's taken every second, it would be considered instantaneous velocity, which is D.
