To determine

The range of wind speed to nearest tenth for a category $4$ hurricane in knots. The below chart gives wind speeds in miles per hour.

$\begin{array}{ccccc}\text{Category}& \begin{array}{l}\text{Wind}\\ \text{Speed}\end{array}& \begin{array}{l}\text{Barometric}\text{pressure}\\ \left[\text{inches}\text{of}\text{mercury}\left(\text{Hg}\right)\right]\end{array}& \begin{array}{l}\text{storm}\\ \text{surge}\end{array}& \text{Damage}\text{potential}\\ 1\left(\text{week}\right)& 75-95\text{mph}& \text{>}\text{28}\text{.94}\text{in}\text{.}& 4-5\text{ft}& \begin{array}{l}\text{Minimal}\text{damage}\text{to}\\ \text{vegetation}\end{array}\\ 2\left(\text{Moderate}\right)& 96-110\text{mph}& 28.50-28.93\text{in}.& 6-8\text{ft}& \begin{array}{l}\text{Moderate}\text{damage}\\ \text{to}\text{houses}\end{array}\\ 3\left(\text{Strong}\right)& 111-130\text{mph}& 27.91-28.49\text{in}.& 9-12\text{ft}& \begin{array}{l}\text{Extensive}\text{damage}\\ \text{to}\text{small}\text{building}\end{array}\\ 4\left(\text{very}\text{strong}\right)& 131-155\text{mph}& 27.17-27.90\text{in}& 13-18\text{ft}& \begin{array}{l}\text{Extreame}\text{structural}\\ \text{damage}\end{array}\\ 5\left(\text{Devastating}\right)& >155\text{mph}& 27.17\text{in}& \text{>18}\text{ft}& \begin{array}{l}\text{Catastrophic}\\ \text{building}\text{failures}\end{array}\end{array}$
