Question 195391This question is from textbook Introductory Algebra
: HURRICANE WIND SPEEDS: as you can see from the table, Katrina was a category 3 hurricane (winds 111-130 miles per hour) and Andrew was a category 5 (winds of more than 155 miles per hour). At landfall, Andrew's winds were 25 miles per hour stronger than Katrina's and 10 miles more than the 155 miles per hour needed to make it a category 5. Find the wind speeds in mph for Katrina and Andrew.This question is from textbook Introductory Algebra
You have something wrong with the way you stated this problem. If Andrew was 10mph faster than 155, it had to be 165 (which it actually was). But the most Katrina could have been was 130 and 25 more than that is only 155. In fact, Katrina's sustained wind speed at 2nd landfall at Buras-Triumph, Louisiana on August 29, 2005 was 125 mph. However, that was a significant reduction from its highest sustained wind speed of 175 mph (Cat 5) the day before. So, in actuality, comparing Andrew to Katrina at landfall for both of them, the difference is 40 mph in favor of Andrew.
