Light travels at a constant speed of 3.0 x 105km/s. The distance between the Sun and the Earth is about 1.5 x 108km. Use the distance = speed x time formula (d = v t) to calculate the time it takes light to travel from the Sun to the Earth. Show your work. Express your result in the appropriate number of significant figures

well, it is two sig figures from the data.
time=distance/speed=1.5E8km/3.0E5km/s=.50E3seconds=5.0E2seconds
time=distance/speed=1.5E8km/3.0E5km/s=.50E3seconds=5.0E2seconds
