The average distance from Earth to Mars is 2.25×10^8 km, and the distance from Earth to Neptune is 4.3514×10^9 km. How much farther is Neptune from Earth than Mars? Express your answer in scientific notation. Do not round your answer.(1 point)
To find the difference between the distances from Earth to Mars and Earth to Neptune, we subtract the distance from Earth to Mars from the distance from Earth to Neptune.
4.3514×10^9 km - 2.25×10^8 km = 4.3514×10^9 km - 0.225×10^9 km = 4.1264×10^9 km
Therefore, Neptune is 4.1264×10^9 km farther from Earth than Mars.
