Solution:

Horizontal distance (range) = horizontal; component of velocity $\times$ time period
$\therefore $ Horizontal range $\alpha$ horizontal component of velocity. Horizontal range $R_{4}>R_{3}>R_{2}>R_{1}$
Therefore, horizontal velocity component, $\left(v_{H}\right)_{4}>\left(v_{H}\right)_{3}>\left(v_{H}\right)_{2}>\left(v_{H}\right)_{1}$
