Question

The planet Mercury is approximately 6 × 10*7 miles from the sun . the distance between the sun and Mars is approximately 2 × 10*8 .About how many times farther from the sun is Mars than Mercury ? A . 2 B . 3 C . 20 D . 30

​

Answer 1

B. 3

Explanation:

Distance between Sun and Mercury = 6x10^7

Distance between Sun and Mars = 2x10^8

Assuming Mars is x times farther from the Sun, implies

(6x10^7)x = 2x10^8

therefore x = (2x10^8)/(6x10^7)

Eliminating common factors( 2x10^7) is common

therefore x = (1x10)/3

x= 3.33

Answer 2

The answer is B

Because Mercury and the Sun are 60,000,00 miles apart and Mars is 200,000,000 miles away from the sun. Divide 200,000,000 and 60,000,000 and you will get 3.3 (Just round)
