5Sarah, a transportation policy analyst, is studying the impact of new transit policies in Chicago. She finds that implementing a new bus rapid transit line reduced average daily commute times by 25%. If the previous average commute time was 48 minutes, and the city plans to expand the system, further reducing the new average time by 20%, what will the final average commute time be after both changes?
