The average distance from earth to mars is 2.25 times 10^8 km, and the distance from earth to neptune is 4.3514 time 10^9 km. how much farther is neptune from earth then 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 average distance between Earth and Mars from the average distance between Earth and Neptune.
The average distance between Earth and Mars is 2.25 × 10^8 km.
The average distance between Earth and Neptune is 4.3514 × 10^9 km.
To subtract these values, we subtract the distance to Mars from the distance to Neptune:
(4.3514 × 10^9 km) - (2.25 × 10^8 km)
Now, let's perform the subtraction:
4.3514 × 10^9 km - 2.25 × 10^8 km = 4.3514 × 10^9 km - 0.225 × 10^9 km
To subtract the numbers, we subtract the coefficients and keep the same exponent:
4.3514 - 0.225 = 4.1264
So, the difference between the distances is 4.1264 × 10^9 km.
Therefore, Neptune is 4.1264 times 10^9 km farther from Earth than Mars.
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 Mars = 2.25 × 10^8 km
Distance from Earth to Neptune = 4.3514 × 10^9 km
Difference in distance = (4.3514 × 10^9) km - (2.25 × 10^8) km
We can subtract the distances by subtracting the coefficients and keeping the larger power of 10:
4.3514 - 2.25 = 2.1014
Since the power of 10 in the larger distance (4.3514 × 10^9 km) is 9, the answer is:
2.1014 × 10^9 km
To find out how much farther Neptune is from Earth than Mars, we need to calculate the difference between their 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.
Subtracting the distance to Mars from the distance to Neptune:
(4.3514 * 10^9) - (2.25 * 10^8)
Calculating this subtraction, we have:
4.3514 * 10^9 - 2.25 * 10^8 = 4.3514 * 10^9 - 0.225 * 10^9
Simplifying, we have:
4.3514 * 10^9 - 0.225 * 10^9 = (4.3514 - 0.225) * 10^9
Performing the subtraction:
4.3514 - 0.225 = 4.1264
The final answer, expressed in scientific notation, is:
4.1264 * 10^9 km
Therefore, Neptune is 4.1264 * 10^9 km farther from Earth than Mars.
