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

$A$ runs $1 \frac{3}{8}$ times as fast as $B$. If $A$ gives $B$ a start of $120 \, m$ and they reach the goal at the same time,the goal is at a distance of (in $m$)

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

In a game,$A$ can give $B$ $25$ points in $75$ and $C$ $18$ points in $90$. How many points can $C$ give $B$ in a game of $120$?

$A$ and $B$ run a $1 \, km$ race. If $A$ gives $B$ a start of $50 \, m$,$A$ wins by $14 \, sec$. If $A$ gives $B$ a start of $22 \, sec$,$B$ wins by $20 \, m$. The time taken by $A$ to run a $1 \, km$ is (in $sec$):
