If you're a fantastic math PhD, then it's just a matter of answering one or two questions for each one (I think Khan gives you more credit towards mastery the faster you answer questions, at least at first). Averaging two questions per topic and taking one minute per question, that's 780 minutes and you're done in 13 hours.
Counting the top-five missions of KA (all calculus, differential equations, linear algebra) that is over 1,000 hours (not to mention statistics). Needless to say, tackling all of the math in KA is a massive undertaking.

We recommend starting at your grade level and doing 1-2 practice sets per day (or 10 practice sets per week). This should take about 10-20 minutes per day. If you find it difficult, completely okay to start at an earlier grade level.
As you practice skills and answer questions, your mastery level for each skill will go up, if you answered correctly, or down, if you miss questions. If you want to make progress more quickly, try a Mastery challenge. Mastery challenges allow you to strengthen the skills you've already practiced in just six questions.

BC Calculus includes everything in AB Calculus, plus a few extra topics. You'll actually get an AB Calculus sub-score when you take the BC exam. So Calculus BC is not necessarily more difficult than Calculus AB. BC Calculus has to move faster because it covers more material, which is what makes it more intense than AB.
