<span> Mitosis involves Prophase, Metaphase, Anaphase, and Telophase.
So you have
13 + 12 + 3 + 2 = 30 cells in mitosis
and
90 + 30 = 120 cells in total
Therefore your ratio of cells in mitosis to total cells is 30 / 120 = 1 / 4. That means mitosis should take up roughly 1/4 of the total cell cycle length. Since the completely cycle takes 24 hours, mitosis would then take (1/4)*24 = 6 hours</span>

Hurricanes are large, spiraling tropical storms that can pack wind speeds of over 160 mph and unleash more than 2.4 trillion gallons of rain a day.[1]
The deadliest U.S. hurricane on record was a Category 4 storm that hit the island city of Galveston, Texas, on Sept. 8, 1900. Some 8,000 people lost their lives when the island was destroyed by 15-ft waves and 130-mph winds.[2]

In the Atlantic, hurricane season starts June 1, while in the Pacific it starts May 15. Both end on November 30.[4]
When they come onto land, the heavy rain, strong winds and heavy waves can damage buildings, trees and cars. The heavy waves are called a storm surge.[5]
40% of the hurricanes that occur in the United States hit Florida.[6]
The difference between a tropical storm and a hurricane is wind speed – tropical storms usually bring winds of 36 to 47 mph, whereas hurricane wind speeds are at least 74 mph.[7]
Hurricanes rotate in a counter-clockwise direction around the eye. The rotating storm clouds create the "eye wall," which is the most destructive part of the storm.[8]
Hurricanes are classified into 5 categories, based on their wind speeds and potential to cause damage. Names can be "retired" if a hurricane has been really big and destructive. Retired names include Katrina, Andrew, Mitch and most recently Sandy.[9]
When the National Hurricane Center began giving official names to storms in 1953, they were all female. This practice of using only women’s names ended in 1978.[10]
The costliest hurricane to make landfall was Hurricane Katrina, a Category 5 storm that slammed Louisiana in August of 2005. Damages cost an estimated $108 billion.[11]
