Question

The formula for the velocity of an object is v=d/t, where v is the velocity of an object, dis the distance traveled, and t is the time elapsed, while the distance is traveled. If you had only this formula to work with, what should your first step be in determining how long it takes for light to reach Earth from the Sun? What additional information do you need to calculate this?

Answer 1

To know the distance between the sun and the earth you need isolate d of the equation:

`v = (d)/(t) \\ d = vt`

and the additional information needed is the velocity of light and the time elapsed to be in the earth
