Explanation

Choice C is correct. It’s given that in the equation $d equals 16 t$ , $d$ represents the distance, in inches, and $t$ represents the number of seconds since an object started moving. In this equation, $t$ is being multiplied by $16$ . This means that the object’s distance increases by $16$ inches each second. Therefore, the best interpretation of $16$ in this context is that the object is moving at a rate of $16$ inches per second.

Choice A is incorrect and may result from conceptual errors.

Choice B is incorrect. This is the best interpretation of $16 t$ , rather than $16$ , in this context.

Choice D is incorrect and may result from conceptual errors.
