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.(1 point)
To find out how much farther Neptune is from Earth than Mars, we can subtract the distance from Mars from the distance to Neptune:
Distance from Earth to Neptune - Distance from Earth to Mars
= 4.3514 × 10^9 km - 2.25 × 10^8 km
To subtract these values, we need to make sure they have the same exponent. Since 10^8 is smaller than 10^9, we can multiply 2.25 by 10 to make it 22.5:
= 4.3514 × 10^9 km - 22.5 × 10^8 km
Now, we can subtract the distances:
= 4.3514 × 10^9 km - 22.5 × 10^8 km
= 4.3514 × 10^9 km - 0.225 × 10^9 km
= (4.3514 - 0.225) × 10^9 km
= 4.1264 × 10^9 km
Therefore, Neptune is 4.1264 × 10^9 km farther from Earth than Mars.
To find how much farther Neptune is from Earth than Mars, we need to calculate the difference between the two distances.
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 calculate the difference, we subtract the distance to Mars from the distance to Neptune:
4.3514×10^9 km - 2.25×10^8 km
To subtract these values, we need to write both numbers in the same scientific notation format:
4.3514×10^9 km - 0.225×10^9 km
Now we can subtract these values:
4.3514 - 0.225 = 4.1264
To express the answer in scientific notation, we write it as:
4.1264×10^9 km
Therefore, Neptune is 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 calculate the difference between the distances.
1. First, subtract the distance to Mars from the distance to Neptune:
Distance from Earth to Neptune - Distance from Earth to Mars
4.3514×109 km - 2.25×108 km
2. Perform the subtraction:
4.3514×109 km - 2.25×108 km = 4.1265×109 km
Therefore, Neptune is 4.1265×109 km farther from Earth than Mars.
