miles from Earth. How much farther is the Sun than the Moon from Earth?

Answer 1

Compute the difference:

Sun − Moon = 9.29×10^7 − 2.389×10^5 miles.

Write both with the same exponent: 2.389×10^5 = 0.02389×10^7, so
9.29×10^7 − 0.02389×10^7 = 9.26611×10^7 miles.

In standard form: 92,661,100 miles (approximately 9.26611×10^7 miles).
