Question

The diameter of Mercury is approximately 4.9×1034.9×103 kilometers. The diameter of Saturn is approximately 1.2×1051.2×105 kilometers. About how many times greater is the diameter of Saturn than the diameter of Mercury?

Answer 1

Answer: 24.49

Step-by-step explanation:

Given: diameter of Mercury =$4.9\times10^3$

diameter of Saturn=$1.2\times10^5$

To find the number of times the diameter of Saturn is greater than the diameter of Mercury, we divide diameter of Saturn by diameter of Mercury, we get

$\frac{1.2\times10^5}{4.9\times10^3}\\=\frac{1.2\times10^{5-3}}{4.9}\\=\frac{1.2\times10^2}{4.9}\\\\=\frac{120}{4.9}=24.49$

The diameter of Saturn is 24.49 times greater than diameter of Mercury .

Answer 2

To get the difference between the two diameters, all you have to do is subtract the smaller diameter (Mercury) from the larger diameter (Saturn) as follows:

Difference between the two diameters =diameter of Saturn-diameter of Mercury
Difference between the two diameters = (1.2*10^5) - (4.9*10^3)
Difference between the two diameters = 115100 km
