The speed of a weak wind is 5 m / s, of a hurricane – 7 times more, and a speed of a storm wind is 1440 m / min.

The speed of a weak wind is 5 m / s, of a hurricane – 7 times more, and a speed of a storm wind is 1440 m / min. How much more hurricane wind speed than curtain wind speed?

v1 = 5 m / s – weak wind speed.
v2 = v1 * 7 = 5 * 7 = 35 m / s – hurricane wind speed.
v2 and v3 have different units. To compare them, let’s translate the speed of the storm wind in m / s:
v3 = 1440 m / min = (1440: 60) m / s = 24 m / s.
Find the difference between v2 and v3:
v2 – v3 = 35 – 24 = 11 m / s.
Answer: hurricane wind speed is 11 m / s higher than storm wind speed.
