Answer:
36 minutes
Explanation:
If we assume that 180 is a fraction of 300, we can simplify it down to 18/30 and then further simplify it to 3/5 (by dividing both by the GCF, 6). It will take 3/5 of an hour for the train to travel 180 km (or 3/5 of the distance it can travel in one hour). 1/5 of an hour is equal to 12 minutes. Therefore 3/5 of an hour is 36 minutes.

Sunspots appear dark in pictures of the Sun as they actually are fairly bright but appear dark against the even brighter background of the surrounding Sun. Thus, the correct option for this question is A.
<h3>What are Sunspots?</h3>
Sunspots may be defined as areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun's surface. Solar flares are sudden explosions of energy caused by tangling, crossing, or reorganizing magnetic field lines near sunspots.
According to the context of this question, sunspots are blotches on the sun that appear dark because they are cooler than the rest of the solar surface.
Astronomers do know they are linked to intense magnetic activity on the sun, which can suppress the flow of hot matter, but much about their structure and behavior remains enigmatic.
Therefore, the correct option for this question is A.
