i have to draw a scale model of the solar system on a map of our schools campus...on the back, the entire height of the map is 1 kilometer. on the other page, we are given the size of the object and then the distance from the sun. the size is given in km and the distance from the sun is given in millions of km. so for the sun, the size is 695,000 km and distance from sun is 0. mercury is 2,440 km and the distance from the sun is 57.9 millions of km. anyone know how to scale these down?
