Verified step by step guidance

1. Identify the given number: 299,800,000 m/s.
2. Scientific notation expresses numbers as a product of a coefficient and a power of ten. The coefficient should be a number between 1 and 10.
3. Move the decimal point in 299,800,000 to the left until you have a number between 1 and 10. This gives you 2.998.
4. Count the number of places you moved the decimal point. In this case, you moved it 8 places to the left.
5. Express the number in scientific notation as \(2.998 \times 10^8\). Round the coefficient to three significant figures to get \(3.00 \times 10^8\).
