Light from the Sun takes 8 minutes and 20 seconds to reach Earth. The speed of light is 300,000 kilometers per second. 1. How far is the Sun from Earth in kilometers? 2. A spaceship starts traveling from Earth towards the Sun at a speed of 1,000 kilometers per second. Every minute, the speed of the spaceship decreases by 20 kilometers per second due to gravity. How long (in hours and minutes) will it take for the spaceship to reach the Sun, assuming this speed reduction continues?
