A train accelerates from rest at a constant rate \( \alpha \) for
P distance \( x_{1} \) and time \( t_{1} \). After that is retards at

W constant rate \( \beta \) for distance \( x_{2} \) and time \( t_{2} \) and comes to the rest. Which of the following relation is correct?
(1) \( \frac{x_{1}}{x_{2}}=\frac{\alpha}{\beta}=\frac{t_{1}}{t_{2}} \)
(2) \( \frac{x_{1}}{x_{2}}=\frac{\beta}{\alpha}=\frac{t_{1}}{t_{2}} \)
(3) \( \frac{x_{1}}{x_{2}}=\frac{\alpha}{\beta}=\frac{t_{2}}{t_{1}} \)
(4) \( \frac{x_{1}}{x_{2}}=\frac{\beta}{\alpha}=\frac{t_{2}}{t_{1}} \)
