After the nose of the train reaches the platform, it takes some number of seconds for the

nose to reach the far end. At that time, the whole train is lined up with the whole platform.

Then after that, it takes the same number of seconds again for the caboose to reach the far end,

and the train to completely clear the platform.

So the total time that there's some overlap between the train and platform is twice the time

the train takes to move the length of the platform, which is also the length of the train.

Distance = (speed) x (time)

180 meters = (speed) x (9 seconds)

speed = (180/9) = 20 meters per second

Q: A 180 meter long train crosses a platform of equal length in 18 seconds what is the speed of the train?

One degree could be equal to any length depending on how far from the point of origin you are making a measurement. It is not normally a function of length. One degree can be broken down into 60 minutes or 360 seconds.

216 seconds is equal to 3 minutes and 36 seconds.

Yes they are equal in length

no, 3600 seconds are equal to 1 hour

"Equinox" comes from the Latin words for equal and night, because it describes the two times each year when day and night are of equal length as the sun crosses the celestial equator.

The equinox occurs in outer space. That is when the sun crosses the equator so that day and night are equal length.
