Reading speed at that age will vary greatly. Reading subtitles while also having to follow the picture takes away focus and that makes it hard much harder for an inexperienced reader. My daughter, who picked up reading very naturally would have been able to follow sub-titles at age 7 without much trouble. My younger, 7-yo son on the other hand, who is more average in reading ability wouldn't be able to keep up with subtitles yet. Average reading speeds at age 7 seem to be 60-100 words per minute where subtitles are more at the 100-150 words per minute range. So for above-average readers, it will be possible but for the average, they won't be able to keep up consistently.
