A project manager is overseeing two teams working on a new software feature. Team A works 8 hours a day for 5 days and completes 40% of the project. Team B works 7 hours a day for 6 days and completes 30% of the project. If both teams continue at the same rate, how many total hours will it take for both teams combined to complete the entire project?
