The diameter of the globe is 40 spm, the diameter of the Earth is 12,000 km. determine the distance from Novosibirsk to Moscow, if on the globe these cities are separated by a distance of 10 cm
Let’s calculate the scale of the globe: 12,000 km / 40cm = 1.2 * 10 ^ 9 cm / 40cm = 3 * 10 ^ 7;
Distance between two cities: 10cm * 3 * 10 ^ 7 = 3 * 10 ^ 8cm = 3000km.
