Answer 1

B) distance from the sun:

Mercury is 57 million km

Venus is 108 million km

Earth is 150 million km

Sum of all 3 = 57 + 108 + 150 = 315 million kilometers. Written in scientific notation =3.15x 10^8

C) 150 million x 10 = 1.5 billion kilometers. This would put Earth close to Saturn which is 1.43 billion Kim’s from the sun.

1.5 billion -1.43 billion = 70 million kilometers

Scientific notation = 7x 10 ^6

D) 70 million km / 28,000 = 2,500 hours.

Scientific notation = 2.5x 10^3
