The problem in the image asks about two theatres playing short films of different lengths. Here's the full breakdown of the question:

---

**Question:**

- **Theatre A** plays a short film of **60 minutes**, whereas
- **Theatre B** plays a short film of **80 minutes**.
  
If both theatres start the films together at **1:00 PM**, at what time will they start a film together again?

---

This is a classic problem of finding the least common multiple (LCM) of two durations, which in this case are 60 minutes and 80 minutes. Once we determine the LCM, we can figure out how much time passes until both films start at the same time again.

Let me calculate that for you.The least common multiple (LCM) of 60 minutes and 80 minutes is 240 minutes. This means that both Theatre A and Theatre B will start their films together again after **240 minutes**, or **4 hours**.

Since they started at **1:00 PM**, they will start together again at **5:00 PM**.

Here are 5 related questions to deepen your understanding:
1. How can you calculate the LCM for three numbers?
2. What is the general method for finding the greatest common divisor (GCD)?
3. Can this problem be generalized to more than two theatres with different film lengths?
4. How would this change if one theatre took breaks between films?
5. What if Theatre A or Theatre B started their films at different times?

**Tip:** When solving problems involving cycles, like this one, finding the LCM helps identify when the cycles coincide again.

Theatre A plays a short film of 60 minutes, whereas Theatre B plays a short film of 80 minutes. If both start a film together at 1:00 PM, at what time will they start a film together again?

Learn how to calculate when two theaters will start their films together again. Theatre A plays a 60-minute film and Theatre B plays an 80-minute film, both starting at 1:00 PM.
