The period of a planet, asteroid, or comet is the amount of time it takes for that body to orbit the Sun (or planet, in the case of a moon). The amount of time it takes to complete one orbit (the period of the planet, P, in seconds), the separation between the planet and the Sun (r, in kilometers), and the speed at which the planet moves (the planet's velocity, v, in kilometers per second) are related by the equation:

P=2r/v
5. Earth travels around the Sun at a speed of 29.8 kilometers per second. At this speed, Earth requires 3.15576107seconds to orbit the Sun once. What is the distance from the Earth to the Sun in kilometers?
