Document Summary
Correct answers are 150,000 inches, or 15,840 feet, or close to three miles. An easy way to calculate the scaled distances is seen from the. For a scaled model of the solar system and nearby stars, adopt a scale where the diameter of the earth is scaled to 1 foot. Earth-moon distance (1 light-second) is 33 feet. comparison between the real size in kilometers and the scaled-size in inches. For the earth"s size (diameter), we have 12,000 km going to 12". So in general, we can convert simply by dividing by 1000 (i. e. , lopping off three zeros) and changing from real-kilometers to scaled inches. So, the size of the sun is 1,392,000 km, so the scaled size of the sun will be 1,392 inches. One this scale, how far would we have to place the sun from the earth? (note, the sun-earth distance is given as.
