Final answer:
To calculate the distance of the Sun from Earth in light-minutes, divide the distance between them by the speed of light and convert to minutes.
Step-by-step explanation:
To calculate the distance of the Sun from Earth in light-minutes, we need to divide the distance between the Sun and Earth (1.5 x 10^11 m) by the speed of light (3 x 10^8 m/s).
This will give us the time it takes for light to travel from the Sun to Earth in seconds. Then, we divide that time by 60 to convert it to minutes.
Distance in light-minutes = (1.5 x 10^11 m) / (3 x 10^8 m/s) / 60
Calculating this gives us a distance of 5 light-minutes. Therefore, the correct answer is a) 5 light-minutes.
