Velocity of light 0001

There are 150 000 000 km between the Sun and the Earth. If the velocity of light in vacuum is 300 000 km/s, how long light takes to reach the Earth?


Clearing "time" in the velocity equation: t = \frac{d}{c} ("c" is the speed of light).
Now is time to solve the equation:

t = \frac{1,5\cdot 10^8\ km}{3\cdot 10^5\frac{km}{s}} = \bf 500\ s
