If the speed of a train is increased by $5 \mathrm{km}/\mathrm{h}$ from its normal speed it would have taken $2 \mathrm{h}$ less to cover $300 \mathrm{km}$. What is its normal speed?

A $200 \mathrm{m}$ long train crosses a platform of double its length in $36 \mathrm{s}$. The speed of the train is:

A train $270 \mathrm{m}$ long is moving at a speed of $25 \mathrm{km}/\mathrm{h}$. It will cross a man coming from the opposite direction at $2 \mathrm{km}/\mathrm{h}$ in:

A train running at $36 \mathrm{km}/\mathrm{h}$ takes $10 \mathrm{s}$ to pass a telegraph pole. How long would it take to cross a platform $110 \mathrm{m}$ long?

A train running at a uniform speed crosses a $122 \mathrm{m}$ long platform in$17 \mathrm{s}$ and a $210 \mathrm{m}$ long bridge in $25 \mathrm{s}$. The speed of the train is:

A train is moving at a speed of $132 \mathrm{km}/\mathrm{h}$. If the length of the train is $110 \mathrm{m}$, how long will it take to cross a railway platform $165 \mathrm{m}$ long?

A train crosses a platform $100 \mathrm{m}$ long in$60 \mathrm{s}$ at a speed of$45 \mathrm{km}/\mathrm{h}$. The time taken by the train to cross an electric pole is:

Two trains$105 \mathrm{m}$ and $90 \mathrm{m}$ long are running at the speed of $45 \mathrm{km}/\mathrm{h}$ and $72 \mathrm{km}/\mathrm{h}$ respectively, in opposite directions on parallel tracks. How much time do they take to cross each other?
