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

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 $1350\, m$?

In a $500\, m$ race,the ratio of speeds of two contestants $A$ and $B$ is $3: 4$. $A$ has a start of $140\, m$. Then,$A$ wins by (in $m$)

In a game of $100$ points,$A$ can give $B$ $20$ points and $C$ $28$ points. The number of points $B$ can give $C$ in a game of $100$ points is:

The respective ratio between the speeds of a car,a train and a bus is $5: 9: 4$. The average speed of the car,the bus and the train is $72 \text{ km/h}$ together. What is the average speed of the car and the train together? (in $\text{km/h}$)

$A$ 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?
