A railroad track has small gaps between sections of,metal rails . Why are those gaps needed?

Because all metal expands when heated. If two railway tracks were to be laid together without any gap they will push against each other when they expand in the day. (This is because of the heat of the sun.) When they cool down at night they will contract against each other and return to their original state pulling against each other. The constant pushing and pulling, due to the change of temperature, will cause the joints between the tracks to weaken. They may also break free from one another, causing derailments of trains, and loss of lives.

The railway engineers always leave a small gap between two rails to compensate for the expansion of the rails

print(output_minutes_as_hours(120))

<h3>How to complete programming in Python?</h3>

The code is written in python.

Firstly, we define a function named "output_minutes_as_hours" and the function accept an argument "orig_minutes". The argument is the time in minutes.

Then, we return answer in hours when we divide the orig_minutes by 60.

Finally, we call the function along with it parameter.
