Answer in scientific notation = 3.9 * 10^5 km
Answer in standard form = 390,000 km
========================================================
Work Shown:
[tex]\text{distance} = \text{(speed)*(time)}\\\\\text{distance} = \left(3\times10^{5}\text{ km/s}\right)*(1.3 \text{ s})\\\\\text{distance} = \left(3\times10^{5}*1.3\right) \text{ km}\\\\\text{distance} = \left(3*1.3\times10^{5}\right) \text{ km}\\\\\text{distance} = 3.9\times10^{5} \text{ km}\\\\[/tex]
The approximate distance is about 390,000 km.
According to NASA, the moon is on average roughly 384,400 km away from Earth. I say "average" because the distance slightly changes as the moon orbits the Earth. Unfortunately the orbit isn't a perfect circle and instead an ellipse. The result we got (390,000) isn't too far off from 384,400.
