Question

the closest distance from venus to earth is about 40,000,000 kilometers. the direct distance from saturn to earth is about 1.2×10^9 kilometers. how many times closer to earth is venus than saturn? write your answer in standard - notation.

Explanation:

Step1: Identify the distances

The distance from Venus to Earth is about 40300000 kilometers, which can be written as $4.03\times 10^{7}$ kilometers in scientific - notation. The distance from Saturn to Earth is about $1.2\times 10^{9}$ kilometers.

Step2: Calculate the difference

We want to find out how much closer Venus is to Earth than Saturn. So we subtract the distance from Venus to Earth from the distance from Saturn to Earth.
$(1.2\times 10^{9})-(4.03\times 10^{7})$
First, make the exponents the same. $4.03\times 10^{7}=0.0403\times 10^{9}$
Then, $(1.2\times 10^{9})-(0.0403\times 10^{9})=(1.2 - 0.0403)\times 10^{9}$
$1.2-0.0403 = 1.1597$
So the result is $1.1597\times 10^{9}$ kilometers.

Answer:

$1.1597\times 10^{9}$
