Question
**Example 6:**

**Scenario:**  
Ronnie has two printing machines that print at different rates.

**Machine A:**  
- Prints 45 shirts every 5 minutes.

**Machine B:**  
- Prints 35 shirts every 15 minutes.

**Question:**  
If he leaves the two machines printing for 2 hours, how many shirts would be printed by both machines combined?

**Calculation Explanation:**
1. **Convert the time of printing into minutes:**
   - 2 hours = 2 × 60 minutes = 120 minutes.

2. **Calculate the total output of each machine over 120 minutes:**

   **Machine A:**
   - It prints 45 shirts every 5 minutes.
   - Number of 5-minute intervals in 120 minutes = 120 / 5 = 24 intervals.
   - Total shirts printed by Machine A = 24 intervals × 45 shirts = 1080 shirts.

   **Machine B:**
   - It prints 35 shirts every 15 minutes.
   - Number of 15-minute intervals in 120 minutes = 120 / 15 = 8 intervals.
   - Total shirts printed by Machine B = 8 intervals × 35 shirts = 280 shirts.

3. **Add the totals from both machines:**
   - Total shirts printed by both machines = 1080 shirts + 280 shirts = 1360 shirts.

**Answer:**  
The two machines would print a combined total of **1360 shirts** in 2 hours.
