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.
