Answer:
Therefore,
Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.
Step-by-step explanation:
Given:
The wind speed near the center of a tornado is represented by the equation,

Where,
d = the distance, in miles
S = the wind speed, in miles per hour.
To Find:
S = ? at d = 4 miles
Solution:
We have
.........Given
Substitute d = 4 in above equation we get,

Rounding the answer to the nearest tenth we have

Therefore,
Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.
Answer: As a fraction, the answer is 3/8 (because 5/8 - 2/8 = 3/8). As a whole number, 3/8ths can be represented by 0.375 (as 0.375 is equal to 3/8). :)
You have to use Pythagoras' theorem for this!
The triangle formed is 6 units across, and 8 units down, which means we can form an equation like this:
a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
c = 10.
The answer is 10 :)
