Step-by-step explanation:
1400 / 4 = 350
Answer: About 10.95 nautical miles
Step-by-step explanation: First, lets find how many minutes the cruise ship can cover in 1 nautical mile.
In order to do that divide 21 nautical miles by 21 and 483 minutes by 21.
21/21 = 1 nautical mile 483/21 = 21 minutes
Now, divide 230 minutes by 21 minutes, which equals about 10.95.
So, in 230 minutes the cruise ship will travel about 10.95 nautical miles.
The area of the shape is the same as
Area of the rectangle - Area of the semi-circle.
From the picture, the length and the width of the rectangle are 11 and 8 respectively so the area of the rectangle will be 8 * 11 = 88 unit^2.
From the picture, the diameter of the semi-circle is 8 and so the radius is 4.
Using the area of a semicircle formula:
A =
A = unit^2.
Hence, the area would be 88 - 25.12 = 62.9 unit^2
