The speed of 20m / s is two and a half times less than the wind speed in a hurricane to find the wind speed.

Since the wind speed during a hurricane is 2.5 times more than 20 m / s, then by increasing this speed by 2.5 times, we get the wind speed during a hurricane:
20 m / s * 2.5 = 50 m / s.
Answer: The wind speed during a hurricane reaches 50 m / s, which is 2.5 times the normal wind.
