To convert wind speeds in miles per hour to knots, divide by 1.15. Use this information and the Saffir-Simpson Hurricane Intensity chart below to answer following Exercises Round to the nearest tenth.

1. What is the range of wind speeds for a Category 4 hurricane in knots?
2. A college student signed up for a new credit card that guarantees her no interest charges on transferred balances for a year. She transferred over a $2523.86 balance from her old credit card.
