To convert the speed of light (671,000,000 miles per hour) into scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.
671,000,000 can be written as 6.71 (the first part of the number) multiplied by 10 raised to the power representing how many places we moved the decimal point to the left to get 6.71.
We can express this as:
671,000,000 = 6.71 × 10^8
Therefore, the correct answer is:
