What is the population density of a country with a total population of 140,000,000 and a total land area of 500,000 (\Km^2\)?

A.

200 persons per \(km^2\)

B.

500 persons per \(km^2\)

C.

350 persons per (\km^2\)

D.

280 persons per \(km^2\)

Correct answer is D

Population density(persons per km) = Total population/Total land Area \(km^2\)
=140,000,000/500,000=280 persons per \(km^2\)

The table above shows the temperature and rainfall distribution of station Z. Study and use it to answer the question.

What is the annual range of temperature for station Z

A.

\(10^o\)C

B.

\(54^0\)C

C.

\(22^o\)C

D.

\(32^o\)C

Correct answer is A

The annual range of temperature is calculated by subtracting the lowest temperature of the year from the highest temperature of the year. From the table, the highest temperature is 32oC (in April) and the lowest is 22oC (in January). Therefore, the annual range of temperature is 32 - 22 = 10oC.
