Lawrence needs to be at his job by 5:00 p.m.

It takes him 20 minutes to ride his bike to his job, 30 minutes to eat dinner, and 45 minutes to do his homework.
Which time does he need to start his homework?

A.3:00 p.m.

B.3:25 p.m.

C.3:35 p.m.

D.4:20 p.m.

The total time Lawrence needs to account for is 20 minutes (bike ride) + 30 minutes (dinner) + 45 minutes (homework) = 95 minutes. To make it to his job by 5:00 p.m., he needs to start working backwards from that time.

5:00 p.m. - 95 minutes = 3:25 p.m.

Therefore, Lawrence needs to start his homework by 3:25 p.m.

The answer is B) 3:25 p.m.

To determine the time Lawrence needs to start his homework, we need to calculate the total time it will take for Lawrence to get to his job, eat dinner, and do his homework.

First, let's add up the time it will take for Lawrence to get to his job, eat dinner, and do his homework:
20 minutes (bike ride) + 30 minutes (dinner) + 45 minutes (homework) = 95 minutes

Now, we need to subtract this total time from the time Lawrence needs to be at his job (5:00 p.m.):
5:00 p.m. - 95 minutes = 3:25 p.m.

Therefore, Lawrence needs to start his homework at 3:25 p.m.

The correct answer is:

B.3:25 p.m.
