Question

Mars is about 7^10 km from the sun. Saturn is about 7^11 km from the sun. About how many times the distance from the sun to mars is the distance from the sun to saturn?

Answer 1

7 times

Explanation:

7^10 = 282475249

7^11 = 1977326743

1977326743/282475249 = 7

Answer 2

Saturn is 10 times more distant from the sun than Mars.

Explanation:

Set M as the distance from the Sun to Mars

Set S as the distance from the Sun to Saturn

M = 7x10^10

S = 7x10^11

" how many times the distance from the sun to mars is the distance from the sun to Saturn?" can be stated as:

S/M

S/M = (7x10^11)/(7x10^11)

S/M = (7/7)*(10^11/10^10)

S/M = 1 x 10^(11-10)

S/M = 1x10^1

S/M = 10
