Question: How many hours did the storm which surpassed Typhoon Nora in 2015, grow from a tropical storm to a Category 5 hurricane?

<P0-S0> Typhoon Nora was the fourth-most intense tropical cyclone on record. <P0-S1>  Originating from an area of low pressure over the western Pacific, Nora was first identified as a tropical depression on October 2, 1973. <P0-S2>  Tracking generally westward, the system gradually intensified, attaining typhoon status the following evening. <P0-S3>  After turning northwestward, the typhoon underwent a period of rapid intensification, during which its central pressure decreased by 77 mb (hPa; 2.27 inHg) in 24 hours. <P0-S4>  The typhoon subsequently weakened and turned northwestward as it approached the Philippines. <P0-S5>  After brushing Luzon on October 7, the system passed south of Taiwan and ultimately made landfall in China on October 10. <P0-S6>  At the end of this phase, Nora peaked with winds of 295 km/h (185 mph) and a pressure of 877 mb (hPa; 25.91 inHg), making it the most-intense tropical cyclone on record (alongside Typhoon Ida in 1958) at the time; however, this pressure has since been surpassed by two other typhoons and one hurricane. <P0-S7>  Once onshore, Nora quickly weakened and dissipated the following day. <SEP> <P1-S0> Typhoon Elsie, known in the Philippines as Typhoon Tasing, was one of the most intense known tropical cyclones to make landfall in the Philippines. <P1-S1>  A powerful Category 5 super typhoon, Elsie formed out of a tropical disturbance on October 13, 1989, and initially moved relatively slowly in an area of weak steering currents. <P1-S2>  On October 15, the storm underwent a period of rapid intensification, attaining an intensity that corresponds to a Category 3 hurricane on the Saffir–Simpson Hurricane Scale. <P1-S3>  After taking a due west track towards the northern Philippines, the storm intensified further, becoming a Category 5 super typhoon hours before making landfall in Luzon. <P1-S4>  After moving inland, the typhoon rapidly weakened to a tropical storm. <P1-S5>  Once back over water in the South China Sea, wind shear prevented re-intensifcation. <P1-S6>  Elsie eventually made landfall in Vietnam on October 22 and dissipated the following day over Laos. <SEP> <P2-S0> Hurricane Wilma was the most intense tropical cyclone ever recorded in the Atlantic basin, as well as the most intense recorded in the western hemisphere until Hurricane Patricia in 2015. <P2-S1>  Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten most intense Atlantic hurricanes ever (along with #4 Rita and #7 Katrina), Wilma was the twenty-second storm, thirteenth hurricane, sixth major hurricane, fourth Category 5 hurricane, and second-most destructive hurricane of the 2005 season. <P2-S2>  A tropical depression formed in the Caribbean Sea near Jamaica on October 15, headed westward, and two days later intensified into a tropical storm which turned abruptly southward and was named "Wilma". <P2-S3>  Wilma continued to strengthen, and eventually became a hurricane on October 18. <P2-S4>  Shortly thereafter, explosive intensification occurred, and in only 24 hours, Wilma became a Category 5 hurricane with wind speeds of 185 mph . <SEP> <P3-S0> Hurricane Patricia was the second-most intense tropical cyclone on record worldwide, behind Typhoon Tip in 1979, with a minimum atmospheric pressure of 872 mbar (hPa; 25.75 inHg). <P3-S1>  Initial development was slow, with only modest strengthening within the first day of its classification. <P3-S2>  The system later became a tropical storm and was named Patricia, the twenty-fourth named storm of the annual hurricane season. <P3-S3>  Exceptionally favorable environmental conditions fueled explosive intensification on October 22. <P3-S4>  A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours—a near-record pace. <P3-S5>  On October 23, the hurricane achieved its record peak intensity with maximum sustained winds of 215 mph (345 km/h). <P3-S6>  This made it the most intense tropical cyclone on record in the Western Hemisphere, and the strongest globally in terms of 1-minute maximum sustained winds. <P3-S7>  Originating from a sprawling disturbance near the Gulf of Tehuantepec, south of Mexico, in mid-October 2015, Patricia was first classified a tropical depression on October 20.
