Two particles $P$ and $Q$ are moving along $x$-axis. Their position-time graph is shown in the figure

Choose the correct options

(1) Graph is passing through origin. Hence, option (1) is correct.
(2) From graph, $Q$ starts at $t=10 \mathrm{s}$.
(3) From the given graph, it is clear that particle $Q$ will overtake the particle $P$ at the distance of $30 \mathrm{m}$ and the time difference of $30 \mathrm{s}$.
