The distance from Earth to the Sun is approximately 93,000,000 miles. Which of the following expresses this distance in scientific notation?

✓ Correct Answer: Option B

To write 93,000,000 in scientific notation, move the decimal point to the left until there is only one non-zero digit before it. This requires moving it 7 places, resulting in 9.3. The exponent will be 7, so it's 9.3 x 10^7.
