1500 golden toads were counted in 1987 within 4 km^2. Calculate the population density.
The golden toad population means the amount of golden toads in an area of 1km^2.
Amount of golden toads in 4km^2 = 1500
Amount of golden toads in 1km^2 = 1500/4 = 375
The golden toads density in 1987 is 375 golden toads per square kilometer.
In 1987, 1500 golden toads were counted within an area of 4 km^2. The population density refers to the number of golden toads in a unit area.
In this case it is 1500/4 = 375 toads per km^2.
The population density of golden toads in 1987 was 375 per km^2.
