The distance between two stations is $440\mathit{k}\mathit{m}$. The two trains start simultaneously from these stations on parallel tracks to cross each other. The speed of one of the train is greater than the other by $5\mathit{k}\mathit{m}∕\mathit{h}.$ If the distance between the two trains after 2 hours of their start is $210\mathit{k}\mathit{m}$, the speed in $\mathit{k}\mathit{m}∕\mathit{h}$ of the trains is:
