Sunita travelled 15 km 368 m by train, 8 km 7 m by bus and 400 m on foot. How much distance she travelled in all?

Options

A. 23.775 kg
B. 23.785 kg
C. 23.675 kg
D. 23.475 kg

Answer

To find the total distance Sunita travelled, we will add the distances she travelled by train, bus, and on foot. Here’s how to do it step by step:

### Step 1: Write down the distances
- Distance travelled by train: 15 km 368 m
- Distance travelled by bus: 8 km 7 m
- Distance travelled on foot: 400 m

### Step 2: Convert all distances to the same unit
To make the addition easier, we can convert all distances to meters:
- 15 km = 15 × 1000 m = 15000 m
- 8 km = 8 × 1000 m = 8000 m
- Distance travelled by train: 15 km 368 m = 15000 m + 368 m = 15368 m
- Distance travelled by bus: 8 km 7 m = 8000 m + 7 m = 8007 m
- Distance travelled on foot: 400 m = 400 m

### Step 3: Add all the distances in meters
Now, we will add all the distances:
- Total distance = Distance by train + Distance by bus + Distance on foot
- Total distance = 15368 m + 8007 m + 400 m

### Step 4: Perform the addition
Now we will calculate:
- 15368 + 8007 = 23375 m
- 23375 + 400 = 23775 m

### Step 5: Convert the total distance back to kilometers and meters
To convert 23775 m back to kilometers and meters:
- 1 km = 1000 m
- 23775 m = 23 km and 775 m (since 23775 ÷ 1000 = 23 with a remainder of 775)

### Final Answer
The total distance Sunita travelled is **23 km 775 m** or **23.775 km**.
