A race was completed by seven participants . Their respective timings to complete the race (in seconds) are given
`13.2, 14.5, 12.9, 13.9, 15.6, 14.1, 12.3`
Find the range of their timings

Answer

To find the range of the timings of the seven participants in the race, we will follow these steps:

### Step 1: Arrange the Data
First, we need to arrange the given timings in ascending order. The timings provided are:
- 13.2
- 14.5
- 12.9
- 13.9
- 15.6
- 14.1
- 12.3

Arranging these in ascending order gives us:
- 12.3, 12.9, 13.2, 13.9, 14.1, 14.5, 15.6

### Step 2: Identify the Maximum and Minimum Values
Next, we need to identify the maximum and minimum values from the arranged data:
- **Minimum value**: 12.3 seconds
- **Maximum value**: 15.6 seconds

### Step 3: Calculate the Range
The range is calculated by subtracting the minimum value from the maximum value:
\[ \text{Range} = \text{Maximum value} - \text{Minimum value} \]
Substituting the values we found:
\[ \text{Range} = 15.6 - 12.3 \]

### Step 4: Perform the Calculation
Now we perform the subtraction:
\[ 15.6 - 12.3 = 3.3 \]

### Conclusion
Thus, the range of the timings is **3.3 seconds**.
