Swati walks 150 meters every day. How many kilometres will she walk in 3 weeks ?

Options

A. 2.04
B. 5.92
C. 4.18
D. 3.15

Answer

To solve the problem step by step, we will follow these calculations:

**Step 1: Calculate the total number of days in 3 weeks.**
- We know that 1 week has 7 days.
- Therefore, in 3 weeks, the total number of days is:
\[ 3 \text{ weeks} \times 7 \text{ days/week} = 21 \text{ days} \]

**Step 2: Calculate the total distance Swati walks in 21 days.**
- Swati walks 150 meters every day.
- To find out how many meters she walks in 21 days, we multiply the daily distance by the total number of days:
\[ 21 \text{ days} \times 150 \text{ meters/day} = 3150 \text{ meters} \]

**Step 3: Convert the distance from meters to kilometers.**
- We know that 1 kilometer is equal to 1000 meters.
- To convert meters to kilometers, we divide the total distance in meters by 1000:
\[ \frac{3150 \text{ meters}}{1000} = 3.15 \text{ kilometers} \]

**Final Answer:**
Swati will walk **3.15 kilometers** in 3 weeks.
