Answer:
B. 3
Step-by-step 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
