The average distance from Earth to Mars is 2.25×108 km, and the distance from Earth to Neptune is 4.3514×109 km. How much farther is Neptune from Earth than Mars? Express your answer in scientific notation. Do not round your answer.(
To find out how much farther Neptune is from Earth than Mars, we need to subtract the distance from Earth to Mars from the distance from Earth to Neptune.
Distance from Earth to Neptune - Distance from Earth to Mars = 4.3514×10^9 km - 2.25×10^8 km
Now we need to subtract the two numbers:
4.3514×10^9 km - 2.25×10^8 km = 4.3514 × 10^9 km
In scientific notation, this is written as 4.3514 × 10^9 km.
To find out how much farther Neptune is from Earth than Mars, we need to subtract the average distance from Earth to Mars from the distance from Earth to Neptune.
Distance from Earth to Mars: 2.25 × 10^8 km
Distance from Earth to Neptune: 4.3514 × 10^9 km
To subtract the two distances, we subtract the exponents and divide the coefficients:
(4.3514 × 10^9) - (2.25 × 10^8) = 4.3514 × 10^9 - 0.225 × 10^9 = 4.1264 × 10^9 km
Therefore, Neptune is approximately 4.1264 × 10^9 km farther from Earth than Mars.
To find out how much farther Neptune is from Earth than Mars, we need to subtract the distance from Earth to Mars from the distance from Earth to Neptune.
The distance from Earth to Mars is 2.25×10^8 km, and the distance from Earth to Neptune is 4.3514×10^9 km.
To do the subtraction, we can simply subtract the two distances:
4.3514×10^9 km - 2.25×10^8 km
To subtract these numbers in scientific notation, we need to make sure the exponents are the same. We can accomplish this by rewriting 2.25×10^8 km as 0.225×10^9 km:
4.3514×10^9 km - 0.225×10^9 km
Now we can subtract the values:
4.3514×10^9 km - 0.225×10^9 km = 4.3514 - 0.225 × 10^9 km
Subtracting the numerical values:
4.3514 - 0.225 = 4.1264
The final answer is 4.1264 × 10^9 km.
