Please help! The average distance from the Sun to the Earth is 1.5 x 10^11 meters and the speed of light is 3 x 10^8 . If distance = rate times time, how many seconds on average does it take for the Sun’s light to reach Earth?

The distance from the Sun to the Earth is 1.5 x 10 8 km (actually it’s 1.496 x 10 8 km on average, but two digits is sufficient for most calculations in this class), or 1.5 x 10 11 m, since there are 10 3 m/ 1 km. The time therefore is 1.5 x 10 11 m / 3.0 x 10 8 m/s = 0.5 x 10 3 s = 500 seconds.
