9. Wind speeds at the center of the hexagonal vortex have been clocked at __ a. 5 kilometers per hour b. 50 kilometers per hour c. 500 kilometers per hour d. 5000 kilometers per hour d. the south pole

## Step 1<br />The problem is asking for the wind speeds at the center of a hexagonal vortex. The options provided are 5 kilometers per hour, 50 kilometers per hour, 500 kilometers per hour, and 5000 kilometers per hour.<br />## Step 2<br />The wind speeds at the center of a hexagonal vortex are typically high due to the nature of the vortex. The vortex is a rotating column of air that can reach high speeds.<br />## Step 3<br />Among the options provided, 500 kilometers per hour is the most reasonable speed for the center of a hexagonal vortex. This is because the other options are either too low (5 kilometers per hour) or too high (5000 kilometers per hour) to be realistic for the center of a vortex.
