`500 cm + 50 m + 5` km is equal to

Options

A. 500 m
B. 555 m
C. 5055 m
D. 55 m

Answer

To solve the question \(500 \, \text{cm} + 50 \, \text{m} + 5 \, \text{km}\), we need to convert all the measurements to the same unit. In this case, we will convert everything to meters (m).

### Step 1: Convert centimeters to meters
We know that:
\[ 1 \, \text{m} = 100 \, \text{cm} \]
To convert \(500 \, \text{cm}\) to meters, we use the conversion:
\[ 500 \, \text{cm} = \frac{500}{100} \, \text{m} = 5 \, \text{m} \]

### Step 2: Convert kilometers to meters
We know that:
\[ 1 \, \text{km} = 1000 \, \text{m} \]
To convert \(5 \, \text{km}\) to meters, we use the conversion:
\[ 5 \, \text{km} = 5 \times 1000 \, \text{m} = 5000 \, \text{m} \]

### Step 3: Add all the values in meters
Now we can add all the values together:
\[ 5 \, \text{m} + 50 \, \text{m} + 5000 \, \text{m} \]
Calculating this gives:
\[ 5 + 50 + 5000 = 5055 \, \text{m} \]

### Final Answer
Thus, \(500 \, \text{cm} + 50 \, \text{m} + 5 \, \text{km} = 5055 \, \text{m}\).
