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 $1000\, m$ race,$A$ beats $B$ by $100\, m$ and $C$ by $200\, m$. By how many meters can $B$ beat $C$ in a race of $1350\, m$?

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?

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

Four runners started running simultaneously from a point on a circular track. They took $200$ seconds,$300$ seconds,$360$ seconds,and $450$ seconds to complete one round. After how much time do they meet at the starting point for the first time? (in seconds)
