Let's break down the problem based on the image you've provided:

### Problem:
- The cheerleading routine is set to last **4 minutes**, with a variation of ±5 seconds.
- We need to:
  - **(a)** Find the least and greatest possible times in **minutes and seconds**.
  - **(b)** Find the least and greatest possible times in **seconds**.

### Solution:

#### (a) Least and Greatest Possible Times in Minutes and Seconds:

1. **Standard time** = 4 minutes = **4 minutes 0 seconds**.
2. **Variation** = ±5 seconds.

   - **Least possible time**: Subtract 5 seconds from 4 minutes.
     - 4 minutes 0 seconds - 5 seconds = **3 minutes 55 seconds**.
   - **Greatest possible time**: Add 5 seconds to 4 minutes.
     - 4 minutes 0 seconds + 5 seconds = **4 minutes 5 seconds**.

So, the least and greatest possible times in minutes and seconds are:
- **Least**: 3 minutes 55 seconds
- **Greatest**: 4 minutes 5 seconds

#### (b) Least and Greatest Possible Times in Seconds:

1. Convert 4 minutes to seconds:
   - 4 minutes = 4 × 60 = **240 seconds**.
2. **Variation** = ±5 seconds.

   - **Least possible time**: 240 seconds - 5 seconds = **235 seconds**.
   - **Greatest possible time**: 240 seconds + 5 seconds = **245 seconds**.

So, the least and greatest possible times in seconds are:
- **Least**: 235 seconds
- **Greatest**: 245 seconds

Would you like further details on any of these steps or have questions?

Here are 5 related questions to deepen your understanding:
1. How do you convert minutes into seconds and vice versa?
2. What happens if the variation was ±10 seconds instead of ±5?
3. Can you explain how to convert hours to minutes and seconds?
4. How would the time change if the routine had a ±30-second tolerance?
5. What is the significance of understanding time limits in sports events like cheerleading?

**Tip**: When working with time units, always remember to check your conversions between minutes and seconds to avoid simple errors.

For competition, the cheerleading team is preparing a dance routine that must last 4 minutes, with a variation of ±5 seconds. Find the least and greatest possible times for the routine in minutes and seconds, and find the least and greatest possible times in seconds.
