Question

The Enhanced Fujita scale rates the intensity of tornadoes based on wind speed and damage caused. An EF5 tornado is estimated to have wind speeds greater than $200$ miles per hour. Write and graph an inequality that represents this situation.

Answer 1

Step 1 : Solve the inequality

We have,

An EF5 tornado have wind speeds greater than $200$ miles per hour

Let the speed of the winds be $=w$

So, the inequality is:

$\Rightarrow w>200$

Step 2 : Solve the graph

We have,

$\Rightarrow w>200$

So, the graph is

Hence, the required inequality is $w>200$ and the required graph is shown above.
