Answer

To find the range of the durations of sunshine in Amritsar for the first 10 days of August 1997, we will follow these steps:

### Step 1: List the given data
The durations of sunshine (in hours) are:
- 9.6, 5.2, 3.5, 1.5, 1.6, 2.4, 2.6, 8.4, 10.3, 10.9

### Step 2: Arrange the data in ascending order
We need to sort the data from the smallest to the largest value:
- 1.5, 1.6, 2.4, 2.6, 3.5, 5.2, 8.4, 9.6, 10.3, 10.9

### Step 3: Identify the minimum and maximum values
From the sorted data:
- Minimum value (Min) = 1.5
- Maximum value (Max) = 10.9

### Step 4: Calculate the range
The formula for calculating the range is:
\[ \text{Range} = \text{Maximum Value} - \text{Minimum Value} \]
Substituting the values we found:
\[ \text{Range} = 10.9 - 1.5 \]

### Step 5: Perform the subtraction
Now, we calculate:
\[ 10.9 - 1.5 = 9.4 \]

### Final Answer
The range of the durations of sunshine is **9.4 hours**.
