Let's solve each problem step by step:

---

Problem 1:

Marianne began her homework at 3:20 pm. She finished it at 4:45 pm. How long did it take Marianne to complete her homework?

#### Solution:
1. Start time: 3:20 pm
2. End time: 4:45 pm

To calculate the elapsed time:
- From 3:20 pm to 4:20 pm is 1 hour.
- From 4:20 pm to 4:45 pm is 25 minutes.

So, the total elapsed time is:
\[ 1 \text{ hour} + 25 \text{ minutes} = 1 \text{ hour and } 25 \text{ minutes} \]

Answer:
\[
\boxed{1 \text{ hour } 25 \text{ minutes}}
\]

Problem 2:

The movie started at 6:11 pm. It lasted 84 minutes. At what time did the movie finish?

#### Solution:
1. Start time: 6:11 pm
2. Duration: 84 minutes

Convert 84 minutes into hours and minutes:
\[ 84 \text{ minutes} = 1 \text{ hour } 24 \text{ minutes} \]

Add this duration to the start time:
- Add 1 hour to 6:11 pm: \( 6:11 \text{ pm} + 1 \text{ hour} = 7:11 \text{ pm} \)
- Add 24 minutes to 7:11 pm: \( 7:11 \text{ pm} + 24 \text{ minutes} = 7:35 \text{ pm} \)

So, the movie finished at:
\[ 7:35 \text{ pm} \]

Answer:
\[
\boxed{7:35 \text{ pm}}
\]

Problem 3:

It takes Frank 47 minutes to get from his house to the store. If he wants to be at the store at 9:00 am, what time does Frank need to leave his house?

#### Solution:
1. Arrival time at the store: 9:00 am
2. Travel time: 47 minutes

To find the departure time, subtract the travel time from the arrival time:
- Subtract 47 minutes from 9:00 am:
- 9:00 am minus 47 minutes is 8:13 am.

So, Frank needs to leave his house at:
\[ 8:13 \text{ am} \]

Answer:
\[
\boxed{8:13 \text{ am}}
\]

Problem 4:

Nemo started his FaceTime conversation with Dory at 4:35 pm. They finally said goodbye at 8:22 pm. How long did the two friends speak?

#### Solution:
1. Start time: 4:35 pm
2. End time: 8:22 pm

To calculate the elapsed time:
- From 4:35 pm to 8:35 pm is 4 hours.
- From 8:35 pm to 8:22 pm is -13 minutes (or 13 minutes less than an hour).

So, the total elapsed time is:
\[ 4 \text{ hours} - 13 \text{ minutes} = 3 \text{ hours } 47 \text{ minutes} \]

Answer:
\[
\boxed{3 \text{ hours } 47 \text{ minutes}}
\]

Problem 5:

Betty Spaghetti spent 1 hour and 23 minutes making spaghetti, and 1 hour and 40 minutes making meatballs. How long did Betty take to make the dinner?

#### Solution:
1. Time spent on spaghetti: 1 hour 23 minutes
2. Time spent on meatballs: 1 hour 40 minutes

Add these times together:
- Hours: \( 1 + 1 = 2 \) hours
- Minutes: \( 23 + 40 = 63 \) minutes

Since 63 minutes is more than 60 minutes, convert 63 minutes into hours and minutes:
\[ 63 \text{ minutes} = 1 \text{ hour } 3 \text{ minutes} \]

Add this extra hour to the total hours:
\[ 2 \text{ hours} + 1 \text{ hour} = 3 \text{ hours} \]
\[ \text{Remaining minutes} = 3 \text{ minutes} \]

So, the total time is:
\[ 3 \text{ hours } 3 \text{ minutes} \]

Answer:
\[
\boxed{3 \text{ hours } 3 \text{ minutes}}
\]
