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 $km/h$):

Two boys,$A$ and $B$,run at $4.5 \text{ km/h}$ and $6 \text{ km/h}$ respectively. $A$ is given a head start of $190 \text{ m}$. If the total course length is $1 \text{ km}$,by what distance (in $\text{m}$) does $B$ win?

$A$ and $B$ run a $5\, km$ race on a round course of $400\, m$. If their speeds are in the ratio $5:4$,how often does the winner pass the other?

In a game,$A$ can give $B$ $20$ points,$A$ can give $C$ $32$ points,and $B$ can give $C$ $15$ points. How many points make the game?

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:
