Answer:
0.00128 m = ;
15 m;
950000 m (950 km)
Step-by-step explanation:
The scale to be used is 1 to 10 billion (1 : 10,000,000,000)
The earth is about 12,760 km (12760000 m) in diameter and about 150 million km (150000000000 m) away from the sun.
Therefore, using this scale, we just have to divide the diameter and distance of the earth from the sun by 10,000,000,000:
Diameter = 12760000 / 10000000000 = 0.00128 m
Distance = 150000000000 / 10000000000 = 15 m
The nearest stars besides the Sun are about 4.3 light-years away (1 light-year equals = [tex]9.5 * 10^{12} km[/tex] = 9500000000000000 m). Therefore, using the scale:
Distance = 9500000000000000 / 10000000000 = 950000 m = 950 km
