A car is running at a speed of 12 km/h. What distance will it cover in 20 minutes ?

Options

A. 2 km
B. 4 km
C. 3 km
D. 3 `(1)/(2)` km

Answer

To solve the problem of how far a car traveling at a speed of 12 km/h will cover in 20 minutes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given values:**
- Speed of the car = 12 km/h
- Time = 20 minutes

2. **Convert time from minutes to hours:**
- Since speed is given in km/h, we need to convert the time from minutes to hours.
- To convert minutes to hours, we use the formula:
\[ \text{Time in hours} = \frac{\text{Time in minutes}}{60} \]
- Therefore,
\[ \text{Time in hours} = \frac{20}{60} = \frac{1}{3} \text{ hours} \]

3. **Use the formula to find distance:**
- The formula to calculate distance is:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
- Substituting the values we have:
\[ \text{Distance} = 12 \text{ km/h} \times \frac{1}{3} \text{ hours} \]

4. **Calculate the distance:**
- Performing the multiplication:
\[ \text{Distance} = 12 \times \frac{1}{3} = 4 \text{ km} \]

5. **Conclusion:**
- The distance covered by the car in 20 minutes is **4 kilometers**.
