Hi there! The answer is 4:06 pm.
Nick gets out of school at 2:25 pm.
He has a 16 minute ride home on the bus, so he'll arrive at home at 2:41 pm.
Next, he goes on a 30 minute bike ride, which will start at 2:41 pm. and thus and at 3:11 pm.
Then he spends 55 minutes doing homework, which starts at 3:11 pm. and will end at 4:06 pm.
The answer is 4:06 pm.
~Hope this helps you!
