9) The formula S = wf- gives the approximate size in kilobytes (Kb) of a compressed video. The variables h and w
35000
represent the height and width of the frame measured in pixels, f is the number of frames per second (fps) the video
plays, and t is the time the video plays in seconds.
a) Solve the equation for t
b) Estimate the time a movie trailer will play if it has a frame height of 320 pixels, has a frame width of 144 pixels,
plays at 15 fps, and has a size of 2370 Kb. Round to the nearest whole number.
