Solar System Model
Kate and Shireen are making a model of the solar system on the ceiling of their classroom.They plan to place their model of the Sun at the southwest corner of the ceiling,and they will mark out the relative distances of the planets along a line from the southwest corner to the northeast corner.The classroom measures 42 ft by 66 ft.Pluto,the farthest planet,is 5.9 * 10^9 km from the Sun.
In order to make the best use of the ceiling space,the girls decide to place their model of Pluto at the northeast corner.They understand that placing Pluto there automatically determines the scale of their model.But in order to know where to place the other planets,the girls need to know what that scale is.
Approximately what distance in the real solar system does 1 centimeter on the model now represent?

答案

凯特和希是一个太阳系的模型在天花板上的教室.他们计划把他们的模型,太阳在西南角的天花板,和他们将标记的相对距离的行星沿路线从西南到东北角.这教室有42英尺66英尺的最远的行星,冥王星,是5.9 *10^9公里的太阳.
为了充分利用空间的天花,她们决定把他们的模型的冥王星在东北角.他们明白,将冥王星有自动确定规模的模型.但要知道在哪里发生其他行星,女孩们需要知道什么,规模.
大约在什么距离真正的太阳能系统1厘米的模型现在代表?
他的意思是这样的
