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 .......... $km/h$.

In a $100 \, m$ race,$A$ runs at $5 \, km/h$. $A$ gives $B$ a start of $8 \, m$ and still beats him by $8 \, s$. Find the speed of $B$ in $km/h$. (in $.14$)

In a race of $600\, m$,$A$ can beat $B$ by $60\, m$ and in a race of $500\, m$,$B$ can beat $C$ by $50\, m$. By how many $m$ will $A$ beat $C$ in a race of $400\, m$?

$A$ can run $500 \ m$ in $30$ seconds and $B$ in $35$ seconds. How many meters start can $A$ give to $B$ in a $1 \ km$ race so that the race may end in a dead-heat?

In a race of $100\, m$,$A$ beats $B$ by $10\, m$ and $C$ by $20\, m$. In a race of $180\, m$,$B$ will beat $C$ by (in $m$):

$A$ can run $23\, m$,while $B$ runs $25\, m$. In a kilometre race,$B$ beats $A$ by (in $m$):
