Jurgen is travelling to Waterloo by bus. He packs for 25 minutes. He then walks to the bus station, which takes 35 minutes. He arrives 60 minutes before his bus leaves. His bus leaves at 6:45 p.m. At what time did he start packing?
(A) 4:45 p.m.
(B) 4:40 p.m.
(C) 4:35 p.m.
(D) 4:55 p.m.
(E) 4:50 p.m.
Jurgen takes $25+35=60$ minutes to pack and then walk to the bus station.

Since Jurgen arrives 60 minutes before the bus leaves, he began packing $60+60=120$ minutes, or 2 hours, before the bus leaves.

Since the bus leaves at 6:45 p.m., Jurgen began packing at 4:45 p.m.

ANSWER: (A)
