EXPLAINATION ➣

initially $\green{\texttt{A is taken as origin }}$ so times at $\green{\texttt{A will be zero }}$

But after some instant $\green{\texttt{C is considered as origin }}$ therefore time at C is zero.

To reduce C=0 we have to subtract by 5 for that we also have to subtract from all position.
