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 the difference in distance between Neptune and Mars, we subtract the distance from Earth to Mars from the distance from Earth to Neptune.
Distance from Earth to Neptune - Distance from Earth to Mars = (4.3514×109 km) - (2.25×108 km)
To subtract these values, we must express them in the same power of 10. We can do this by writing 4.3514×109 km as 4.3514×108×10 km.
Now we can subtract the values:
(4.3514×108×10 km) - (2.25×108 km) = 4.3514×109 km - 2.25×108 km
Since these values have the same power of 10, we subtract the coefficients:
= 4.3514×108 - 2.25×108 km
= 2.1014×108 km
The difference in distance between Neptune and Mars is 2.1014×108 km.
To find out how much farther Neptune is from Earth than Mars, we need to calculate the difference in their distances.
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:
4.3514×10^9 km - 2.25×10^8 km = 4.1285×10^9 km
Therefore, Neptune is 4.1285×10^9 km farther from Earth than Mars.
To find out how much farther Neptune is from Earth than Mars, you need to subtract the distance from Earth to Mars from the distance from Earth to Neptune.
The distance from Earth to Mars is given as 2.25×10^8 km.
The distance from Earth to Neptune is given as 4.3514×10^9 km.
So, to find the difference, subtract the distance to Mars from the distance to Neptune:
4.3514×10^9 km - 2.25×10^8 km
To subtract these values, adjust the exponents so that they have the same power of 10:
4.3514×10^9 km - 0.225×10^9 km
Now, subtract the values:
4.3514 - 0.225 = 4.1264
Finally, we can express the result in scientific notation:
4.1264 × 10^9 km
Therefore, Neptune is approximately 4.1264×10^9 km farther from Earth than Mars.
