Wind speeds are measured like car and truck speeds. They are measured at the rate they travel in miles per hour.

(Remember a car driving in front of Brooks Hill School should be traveling at 15mph. A car traveling on the Highway 90, the NY State Thruway travels at 65mph.)
I am interested in wind speed today. The lake has white caps. I wondered what the wind speed is, and how high the wind speed is when there are white caps. I think this will involve a little math.

The Webster weather says the wind speed is 21mph. But our tree branches are swaying, and the waves are full of white caps. According to to the wind speeds, (measured by miles per hour on a scale called the Beaufort number,) the wind would be about 25-30mph.

If a normal breeze is 8 mph, how much greater is the speed of 21mph?
If a normal breeze is 8 mph, how much greater is the speed of 21mph?
If the wind increases, (like the weather folks suggest) to 40 mph, how much above normal is that?
If the wind increases, (like the weather folks suggest) to 40 mph, how much above normal is that?
How did you solve that? Did you regroup? Did you use a number line? Did you use mental math?

Below is a table for the classification of wind speeds. A Beaufort Scale shows measurement as well. This table is what meteorologists, (people who study weather) use to explain wind speeds.

Right now, the wind speed in Webster, NY is 19mph. This is a number 3 on the Beaufort Scale. The weather bureau classifies this as a gentle-moderate breeze. Indications currently are that there are small waves lashing on the shore.

Do you think if the winds were predicted to be 40 mph, I should plan to go fishing in a 24 foot (small-ish) motor boat? Why or why not?

The pictures above are all taken in the Library of Congress building in Washington. The pictures are of the ceilings, walls, and floors. Each of these pictures show amazing math work. Yes, math was a key part of the designing and construction of these beautiful pieces.
