The distance between Reeta's house and her office is 14 km. She covers 10 km 65 m by scooter, 3 km 75 m by bus and the rest on foot. How much distance does she cover by walking?

Answer

To find out how much distance Reeta covers by walking, we will follow these steps:

### Step 1: Convert all distances to the same unit
We need to convert kilometers to meters because some distances are given in meters.

1 kilometer (km) = 1000 meters (m)

- The total distance from Reeta's house to her office is:
\[ 14 \text{ km} = 14 \times 1000 = 14000 \text{ m} \]

### Step 2: Convert the distances covered by scooter and bus to meters
- Distance covered by scooter:
\[ 10 \text{ km} 65 \text{ m} = (10 \times 1000) + 65 = 10000 + 65 = 10065 \text{ m} \]

- Distance covered by bus:
\[ 3 \text{ km} 75 \text{ m} = (3 \times 1000) + 75 = 3000 + 75 = 3075 \text{ m} \]

### Step 3: Calculate the total distance covered by scooter and bus
Now, we add the distances covered by scooter and bus:
\[ \text{Total distance covered by scooter and bus} = 10065 \text{ m} + 3075 \text{ m} = 13140 \text{ m} \]

### Step 4: Calculate the distance covered by walking
To find the distance Reeta covers by walking, we subtract the total distance covered by scooter and bus from the total distance to her office:
\[ \text{Distance covered by walking} = \text{Total distance} - \text{Total distance covered by scooter and bus} \]
\[ \text{Distance covered by walking} = 14000 \text{ m} - 13140 \text{ m} = 860 \text{ m} \]

### Final Answer
Reeta covers **860 meters** by walking.
