Given that a car's distance from a stop sign t seconds since it started moving is represented by d=t2-2t determine the car's average speed over each interval of elapsed time

Average speed =t-2t

Explanation:

Equation given for Average speed = Total distance/Elapsed time

Given: Total distance=d=t^2-2t

Elapsed time= t

Substituting into the equation

Average speed = t^2-2t/t

Dividing both numerator an denomination with t

Average speed=t-2t

are their multiple choices ?

explanation:

are there options? cause you ain’t. real specific
