Answer:
9 pm
Explanation:
If the local mean time at 45° W is 12:00 noon, what will be the local mean time at 90°E?
Solution:
The lines of longitude run from north to south, measuring distance from east to west of the prime meridian. The line of longitude are used to measure time between different locations.
Each 15° = 1 hour, 1° = 4 minutes
Change in longitude = 45° + 90° = 135°
Change in time = 135° * (1 hour per 15°) = 9 hours
Final destination time = initial time + change in time
Final destination time = 12 noon + 9 hours
Navigation rules are those that regulate the way boats are to navigate the water. They are much like the rules of the road for cars.
Their main objective is to establish a consistent way to navigate safely and avoid collisions and accidents.
A census<span> is the procedure of systematically acquiring and recording </span>information<span> about the members of a given </span>population. It is a regularly occurring and official count of a particular population.[1]<span> The term is used mostly in connection with </span>national population and housing censuses<span>; other common censuses include agriculture, business, and traffic censuses.
