I did not get a solution with time = 1.pm. I conveniently changed it to 1.00 am 
For Anna,
time = t, speed = r
For the competitor,
time = t-1 rate = 3r/2
When the person overtakes Ana, the distance they have travelled is the same. ie.
tr = (t-1)3r/2
Solving this, we get t = 3
So anna's distance = tr = 3*r = 3r
Hence E

AFAIK, there's no such thing as 12:00 am. Its midnight or 00:00 am and noon or 12 pm.
Anyway, assuming 12:00 am is midnight, and 1 pm is 13 hours away.
So Anna has 13 hours lead on the other guy. In 13 hours, she's travelled 13r. The other guy travels 0.5 r on Anna every hour, so takes 26 hours to catch up, in which Anna has travelled another 26r distance. Thus Anna's distance from the bridge is 39r.
Assuming that 12:00 am was noon, the guy is 1 hour behind Anna. At 1:00, when the guy was at the bridge, Anna was already r distance away. The guy gains 0.5 r over Anna every hour, so covers the r distance between them in 2 hours, in which Anna has travelled 2r more, totalling 3r.
