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)
km
To find 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: 4.3514×10^9 km
Distance from Earth to Mars: 2.25×10^8 km
Calculating the difference:
4.3514×10^9 km - 2.25×10^8 km = 4.1265×10^9 km
Therefore, Neptune is 4.1265×10^9 km farther from Earth than Mars.
Incorrect
Apologies for the confusion. Let's correct the answer.
To find 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: 4.3514×10^9 km
Distance from Earth to Mars: 2.25×10^8 km
Calculating the difference:
4.3514×10^9 km - 2.25×10^8 km = 4.1265×10^9 km
Therefore, Neptune is 4.1265×10^9 km farther from Earth than Mars.
To find the difference in distance between Neptune and Mars, we need to subtract the 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
Subtracting these two distances, we get:
4.3514×10^9 km - 2.25×10^8 km
To subtract these two numbers, we need to ensure that they have the same power of 10. We can do this by rewriting the first number in scientific notation:
4.3514×10^9 km - 0.225×10^9 km
Now we can subtract the two:
(4.3514 - 0.225) × 10^9 km
Simplifying:
4.1264 × 10^9 km
Therefore, Neptune is approximately 4.1264 × 10^9 km farther from Earth than Mars.
To calculate 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.
Given:
Distance from Earth to Mars = 2.25 × 10^8 km
Distance from Earth to Neptune = 4.3514 × 10^9 km
To find the difference, we subtract the distance to Mars from the distance to Neptune:
Difference = Distance to Neptune - Distance to Mars
Difference = (4.3514 × 10^9 km) - (2.25 × 10^8 km)
To subtract the distances, we need to make sure they have the same exponent. We can convert the distance to Mars to scientific notation with an exponent of 9:
Distance to Mars = 2.25 × 10^8 km = 2.25 × 10^8 × 10^1 km = (2.25 × 10^8) × (10^1 km) = 2.25 × 10^9 km
Now, we can subtract the distances:
Difference = (4.3514 × 10^9 km) - (2.25 × 10^9 km)
To subtract these values, we subtract the coefficients and keep the same exponent:
Difference = (4.3514 - 2.25) × 10^9 km
To calculate the difference between Neptune and Mars, we subtract the coefficients:
Difference = 2.1014 × 10^9 km
Therefore, Neptune is 2.1014 × 10^9 km farther from Earth than Mars.
