Q. Video games create a sense of motion by displaying still images, called frames, in rapid succession. A popular video game displays

60

frames per second. Which of the following equations shows the total number of frames,

f

, that the video game will display in

s

seconds?

\newline

Choose

1

answer:

\newline

(A)

f=s+60

\newline

(B)

f=\frac{s}{60}

\newline

(C)

f=\frac{60}{s}

\newline

(D)

f=60s

Understand relationship: Understand the relationship between frames and seconds. $\newline$ The total number of frames displayed by the video game is the product of the number of frames per second and the number of seconds, i.e., $\text{total frames} = \text{frames per second} \times \text{seconds}.$
Identify given values: Identify the given values. $\newline$ Frames per second: $60$ $\newline$ Number of seconds: $s$ $\newline$ Total number of frames: $f$
Write equation: Write the equation for the total number of frames. $\newline$ Total frames = Frames per second $\times$ Number of seconds $\newline$ $f = 60 \times s$
Match with options: Match the equation with the given options. $\newline$ The correct equation that represents the total number of frames in $s$ seconds is $f = 60s$ , which corresponds to option $(D)$ .
