City Guilds Model Questions Vol1 2021 Information Technology Question 35

A presenter prepares a PowerPoint file with 30 slides. Each slide contains on average: - 2 images, each of size 500 KB - 1 video clip of 5 seconds, encoded at 2 Mbps (720 p) The presentation also includes a background music track of 3 minutes, encoded at 128 kbps. Assuming no additional compression beyond the given rates: (a) Calculate the total file size of the presentation in megabytes (MB), rounded to two decimal places. (b) If the presentation is delivered at a constant pace covering all slides and the music track, and the video clips play concurrently with the slide narration (i.e., video time does not add to the total duration), what is the average time allocated per slide in seconds? Round to the nearest whole second. Give the answer as "size MB, slide seconds".
