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:

4.3514×10^9 km - 2.25×10^8 km = 4.129×10^9 km

Apologies for the mistake. Let's recalculate:

4.3514×10^9 km - 2.25×10^8 km = 4.1269×10^9 km

Therefore, Neptune is approximately 4.1269×10^9 km farther from Earth than Mars.

To find the difference between the high end and the low end of the range, we subtract the low end from the high end of the range:

2.329×10^(-2) cm/hr - 6.849×10^(-4) cm/hr = 2.2601×10^(-2) cm/hr

Therefore, the difference between the high end and the low end of the range is approximately 2.2601×10^(-2) cm/hr.
