Mathematics 1

When 20 added to 30 can't be 40,
but at the same time it can't be 60.
A 30 minute cycle after starting at 20
Takes us to which point closer to 60
It definitely takes me away from 40.
A pace which I can't seem to pace
I thought it could be a good 70.
But that is so difficult to place.
A 70 in time would be 1:10
But yet a 20 plus 30 in time isn't.
I place the 30 after the 20
And after a grand struggle
I place the 3 after the 2
That is when I get a good old 5.
And so definitely a 30 and 20
Had to make the so difficult 50.
Understanding this struggle
Is in the pace-
a struggle my brain seem to face.
