In a race of $300 \text{ m}$,$A$ beats $B$ by $15 \text{ m}$ or $5 \text{ s}$. $A$'s time over the course is:

In a $500\, m$ race,the ratio of the speeds of two contestants $A$ and $B$ is $4:5$. $A$ has a start of $140\, m$. Then $A$ wins by (in $m$):

In a $100\, m$ race,Kamal defeats Bimal by $5$ seconds. If the speed of Kamal is $18\, km/h$,then the speed of Bimal is .......... $km/h$.

$A$ and $B$ take part in a $100\, m$ race. $A$ runs at $5\, km/h$. $A$ gives $B$ a start of $8\, m$ and still beats him by $8\, s$. The speed of $B$ is (in $km/h$):

At a game of billiards,$A$ can give $B$ $6$ points in $50$ and he can give $C$ $13$ points in $65$. In a game of $55$ points,how many points can $B$ give $C$?

In a game of $100$ points,$P$ can give $Q$ $10$ points and $R$ $28$ points. Then $Q$ can give $R$ (in points) how many points?
