Let distance between p and q become 120 after t s. 
And are at point C and D. 
Now, because p and q are moving with equal speed hence, CDO will be a right angled triangle. 
Distance covered in time t by p and q=12t
Therefore after 12.5 s p is at 240-12*(12.5)
=90m from 0
q is at 300-(12*12.5)
=150 form O
Now q speed of q has become 15m/s
Time taken by q to reach point O
Time taken by p to reach point O
Hence p will reach first at point O
