Question

The diameter of Mercury is approximately4.9×103 kilometers. The diameter of Saturn is approximately 1.2×105 kilometers. About how many times greater is the diameter of Saturn than the diameter of Mercury?

Answer 1

Answer: 378.7 kilometers (maybe, I am not sure)

Mercury: 4.9 * 103 = 504.7 kilometers

Saturn: 1.2 * 105 = 126 kilometers.

Why on earth is Mercury's diameter greater than Saturn's -

504.7 - 126 = 378.7 kilometers
