Question
How long does it take light from the sun to reach the earth? Assume the earth's distance from the sun to be $1.50 \times 10^{8} \mathrm{~km} .$
Step 1
We know that 1 kilometer is equal to 1000 meters. So, the distance in meters is $1.50 \times 10^{8} \mathrm{~km} \times 1000 = 1.50 \times 10^{11} \mathrm{~m}$. Show more…
