Final answer:
To calculate the time it takes for light to travel 1.50 billion km, divide the distance by the speed of light (3 × 10⁵ km/s), which results in 5000 seconds.
Step-by-step explanation:
The question asks how much time (in seconds) it takes for light to travel a distance of 1.50 billion kilometers. To solve this problem, we first note that the speed of light is approximately 3 × 10⁵ km/s. To calculate the time it takes for light to cover any distance, we use the formula time = distance/speed.
Given the distance (1.50 billion km), we then perform the calculation as follows:
Time (in seconds) = Distance (in km) / Speed of light (in km/s)
Time = 1.50 × 10⁹ km / 3 × 10⁵ km/s
Time = (1.50 / 3) × 10⁴ s
Time = 0.50 × 10⁴ s
Time = 5 × 10³ s
Therefore, it takes 5000 seconds for light to travel a distance of 1.50 billion kilometers.
