Dear Abhay,
According to your question;
Time taken=12.5hrs=12.5*60*60=45000sec.
θπ + π/24 = 25π/24.
θ = ω t + (α  t) / 2.
Since motion of minutes hands in clock is in constant angular velocity, α = 0.
θ = ω t 
on substituting the values we value of; ω= 0.23 π * 10-4 rad/sec.
we know,
v= r ω
here on calculating v we get;
v = 0.92 π * 10-4 cm/s = 3.14 * 10-4 cm/s.
Approve if my answer helped you.
