How long should be Speaking Part 3 answers be?
There is no set number of sentences or number of seconds the examiner is looking for. However, about 45 seconds is a good rule of thumb. If you're able to produce the language you need automatically (in other words, you have good fluency), then this should give you enough time to answer the question directly and fully develop your answer.
Use Chris' Part 3 strategy from Module 5 of the Speaking Academy course to develop your answer effectively.
