(B) Let the speed of $B$ be $v$. Then the speed of $A$ is $\frac{3}{2}v$.Ratio of speeds of $A$ and $B$ is $A:B = \frac{3}{2}v : v = 3:2$.This means that in a race where $A$ covers $3 \, m$,$B$ covers $2 \, m$.In this scenario,$A$ gains $(3 - 2) = 1 \, m$ over $B$ for every $3 \, m$ of the race length.We are given that $A$ gives $B$ a start of $300 \, m$,meaning $A$ needs to gain $300 \, m$ over $B$ to reach the winning post simultaneously.If $1 \, m$ gain corresponds to a race length of $3 \, m$,then $300 \, m$ gain corresponds to a race length of $3 	imes 300 = 900 \, m$.

$A$'s speed is $1 \frac{1}{2}$ times of $B$'s speed. In a race,$A$ gives $B$ a start of $300 \, m$. How long should the race course be so that both reach the winning post simultaneously? (in $m$)
