After school, Diana had a science club meeting for 1 hour and 20 minutes, followed by a choir rehearsal that lasted for 1 hour and 35 minutes. If Diana got out of school at 1:40 P. M., what time did the choir rehearsal end?

3:15PM

Step-by-step explanation:

If If Diana got out of school at 1:40 P.M, this and spent 1 hour 35 minutes at the rehearsal, to know the time that the choir rehearsal ends, we will have to add the time spent at rehearsal to the time he got out of school;

1:40 P.M + (1hr 35 minutes)

1:40 P.M + 1 hr = 2:40PM

2:40PM + 35mintes = 2:40PM + (20mintes) +15 minutes

[2:40PM + (20mintes)] +15 minutes = 3:00pm + 15 minutes

3:00pm + 15 minutes = 3:15PM

Hence the choir rehearsal ends at 3:15PM
