<span>0.05 arc-second = 1 degree/72000 = (pi
radians)/(180*72000) = 2.424 x 10^(-7) radians</span>
<span>The distance is roughly: </span>
<span>R*(theta) = (600 light-years)*2.424 x 10^(-7) = 0.00014544 light-years = 1.275
light-hours = (3600 seconds)*(3 x 10^8 m/s)*(1.275) = 1.38 x 10^12 meters. </span>
Answer:
Diameter of the star,
Step-by-step explanation:
Given that,
Angular diameter of the star, angle,
Distance,
We need to find the diameter of the supergiant star Betelgeuse. The relationship between the diameter of star and angle subtended is given by :
, d = diameter
or
Hence, this is the required solution.

Answer:
5 hours
Step-by-step explanation:
If he drove 360 miles in 6 hours, that means he drives 60 miles per hour.
300 divided by 60 is 5, so he will need to drive for 5 more hours
