Answer

To find out how much distance Raghav walked on Thursday, we can follow these steps:

### Step 1: Write down the total distance walked in four days.
Raghav walked a total of 42.25 km in four days.

### Step 2: Write down the distances walked on each of the first three days.
- Distance walked on Monday: 8.25 km
- Distance walked on Tuesday: 7.52 km
- Distance walked on Wednesday: 11.27 km

### Step 3: Calculate the total distance walked in the first three days.
To find the total distance walked from Monday to Wednesday, we add the distances:

\[ \text{Total distance from Monday to Wednesday} = 8.25 + 7.52 + 11.27 \]

Calculating this step-by-step:
1. Add Monday and Tuesday:
\[ 8.25 + 7.52 = 15.77 \text{ km} \]
2. Now add Wednesday's distance:
\[ 15.77 + 11.27 = 27.04 \text{ km} \]

### Step 4: Calculate the distance walked on Thursday.
To find the distance Raghav walked on Thursday, subtract the total distance walked from Monday to Wednesday from the total distance walked in four days:

\[ \text{Distance on Thursday} = \text{Total distance} - \text{Total distance from Monday to Wednesday} \]

Substituting the values:
\[ \text{Distance on Thursday} = 42.25 - 27.04 \]

Calculating this:
\[ 42.25 - 27.04 = 15.21 \text{ km} \]

### Final Answer:
Raghav walked **15.21 km** on Thursday.
