Question

The distance of planet Jupiter from the Sun is approximately 7.8 ⋅ 10^8 kilometers, and the distance of planet Saturn from the Sun is 1.5 ⋅ 10^9 kilometers. About how many more kilometers is the distance of Saturn from the Sun than the distance of Jupiter from the Sun?

Answer 1

Answer:

$0.72*10^{9}\ km$  or $720,000,000\ km$

Step-by-step explanation:

we have

The distance of planet Jupiter from the Sun is $7.8*10^{8}\ km$

The distance of planet Saturn from the Sun is $1.5*10^{9}\ km$

we know that

To find how many more kilometers is the distance of Saturn from the Sun than the distance of Jupiter from the Sun, calculate the difference between the two distances

but first

$7.8*10^{8}\ km=7.8*10^{8}*\frac{10}{10}=0.78*10^{9}\ km$

therefore

$1.5*10^{9}\ km-0.78*10^{9}\ km=0.72*10^{9}\ km$

$0.72*10^{9}\ km=720,000,000\ km$

Answer 2

Answer: C.) 7.2 x 10^8

Step-by-step explanation:

Jupiter to Sun= 7.8 x 10^8

Saturn to Sun= 1.5 x 10^9

1.5 x 10^9---> 15 x 10^8

(15-7.8) (10^8 - 10^8) =

7.2 x 10^8
