Question

A salesperson is trying to sell you a phone that has 16gb of memory saying, “that’s enough space to record an hour of high quality video!” this salesperson is probably wrong, but in which direction? would you have more than enough memory or not enough?

Answer 1

more than enough because a high quality is 312 kilo bytes per second so 312 times 60 times 60 would equal 1123200

Answer 2

A 16GB memory has the capacity to hold much more than an hour of high quality video. The quality of a video determines how much space it will occupies. An average top quality video can not be more than 3.6 GB in size. This means that, a 16 GB memory will hold more than fours hours long video recording. It can be much more than this is the video is of low quality.
