Two cars of masses $m_{1}$ and $m_{2}$ are moving in circles of radii $r_{1}$ and $r_{2}$ respectively. Their angular speeds $\omega_{1}$ and $\omega_{2}$ are such that they both complete one revolution in the same time $t$. The ratio of the linear speed of $m_{1}$ to the linear speed of $m_{2}$ is:

• A
  $r_{1}: r_{2}$
• B
  $T_{1}^{2}: T_{2}^{2}$
• C
  $\omega_{1}^{2}: \omega_{2}^{2}$
• D
  $m_{1}: m_{2}$
