46:53 Hey, Neil, it is Sourav. So, I think the way to think about it in terms of the margin expansion, it really will be driven by how quickly we get back to 2019 levels of revenue, right? So the $100 million to $150 million, we are still very, very confident we can deliver that in incremental EBITDA based on 2019 numbers. But all depends on when we get back to the revenue. And frankly, if we get back via rate first, which it looks like we will, obviously you benefit more on the margin front as a result of that. So yes, there is definitely possibility that you end up getting more of a margin expansion as a result of coming back to '19 levels via rate. 47:33 As it relates to where we stand on our initiatives, we talked about it in sort of three big buckets. One is the reduction of management staffing at all our hotels, and it was very hotel specific. We went through every single hotel on sort of zero-based budget and figured out what the ideal staffing level is on -- at a normalized level. And I am happy to report that we had said about 25% to 30% of management staffing would be reduced permanently and that it has been the case, and that is baked into our 2022 budgets. 48:05 The second big bucket was reduction in Above Property charges, which if you listened to the Marriott call, that has also resulted in savings and can -- will continue to result in savings. That is also baked in. The last bucket was sort of twofold. One, as you said, is the modification or elimination of certain brand standards, and then also leveraging technology to drive improved productivity. I will say, of the $100 million to $150 million, 60% we have already initiated, and we are well underway to initiate the balance 40%, which is really the third bucket of brand standards and technology implementation. 48:46 On the brand standards piece, there are a lot of changes that have already taken place, whether that is removal of compendiums or it is making the long stocks optional or relaxation of robes and slipper standards at the premium brands, and including flexibility of operating hours for the club lounge. Minimum hours that are not only for the club lounge but also premium restaurant, as well as relaxation of whether you need premium restaurants at non-resort hotels. So we have made significant progress on the brand standard front. I think the piece which we are still testing right now is housekeeping, and we will have an answer on that sometime middle of this year, but certainly not going back to where we were in 2019. It is really about providing more optionality and flexibility to the guest, but still making sure there is that guest satisfaction level that is needed for the respective brands. So hopefully that gives you some color.
