QUIZ 1

Solve following mathematical word problems on Hurricane Math.

1. Tropical storms become hurricanes when their winds reach 74 miles per hour. After two days,tropical storm Math has wind speeds of 55 miles per hour. How much faster will the winds have to become for Tropical Storm Math to become Hurricane Math?

2. The speed at which a hurricane moves over the surface of the earth is determined by tracking its eye. The eye of Hurricane Math is moving at 15 miles per hour. How long will it take to reaches the coastline still some is 360 miles away?

3. The size of a hurricane is measured from the outermost rainband on one side of the hurricane across the storm through the center of the eye to the outermost rainband on the opposite side. The largest hurricane of the season thus far measured 273 miles wide. Hurricane Math measures 425 miles. How much bigger is Hurricane Math

4. The hurricanes creates a bulge of ocean water called a storm surge beneath its eye. Hurricane Math is now a category 4 hurricane. The storm surge measures 15 feet. If the top of buildings along a beach are 60 feet above sea level, how much of the buildings will escape the storm surge?

5. The highest recorded storm surge was 42 feet. How much would Hurricane Math’s storm surge have to increase to break the record?

6. As Hurricane Math approached the coast, an evacuation of three communities was ordered by local officials. Pine Grove has a population of 6,213, Stoneville has a population of 4.011 and Kingsley has a population of 2,832. How many people were evacuated?

7. After Hurricane Math passed over the area, the evacuation order was lifted and the people returned to their homes. Over the next few weeks, reports of damage were totaled. Pine Grove reported $115, 264 in damage, Stoneville reported 236,096 and Kingsley $436, 869. What was the total cost of damages rounded to the nearest thousand. If the state and federal government promised $500,000 in aid, how much would the local people have to raise by themselves.

8. Below is a chart for the number of tropical storms and hurricanes for the years 1989-1998. Use the information to complete the following.
