I tried to figure it out but the best answer I can get is 32. I don't know which conversion factor to begin.

Question 2:

IF the speed of light is 186,000 mile per second, how long (in hours) does it take the light from the sun to reach the planet Pluto, if it is 2,763,000,000 miles from the sun?

Answer is: 4.13 hr (rounded)

Am I suppose to convert the distance to time? If so, how do I go about doing that.

Thank you,
