This problem can easily be completed if we go through it step by step.
1. Nick has a 15 minute ride home on the bus from school at 2:25 p.m.
2:25 p.m + 15 min = 2:40 p.m.
2. He goes on a 30 minute bike ride after arriving home at 2:40 p.m.
2:40 p.m + 30 min = 3:10 p.m.
3. He spends 55 minutes doing homework at 3:10 p.m.
3:10 p.m. + 55 min = 4:05 p.m.
Ergo, Nick finished his homework at 4:05 p.m.
