Question

you perform an experiment to measure the speed of a car over time. the results are shown in the graph below. what is the best inference for the speed of the car after 12 seconds? a. 23 m/s b. 27 m/s c. 25 m/s d. 28 m/s

Explanation:

Step1: Locate 12 seconds on the x - axis

Find the position corresponding to 12 seconds on the time (x) axis.

Step2: Estimate the speed on the y - axis

Move vertically from \(x = 12\) to the graph and then horizontally to the speed (y) axis. The value is closest to \(25\ m/s\).

Answer:

C. \(25\ m/s\)
