A person covers a distance of 12km, while walking at a speed of 4km/h.How much distance he would cover in same time, if he walks at a speed of 6 km/h?

Answer

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

### Step 1: Calculate the time taken to cover 12 km at a speed of 4 km/h.
We can use the formula for time:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]
Here, the distance is 12 km and the speed is 4 km/h.

\[ \text{Time} = \frac{12 \text{ km}}{4 \text{ km/h}} = 3 \text{ hours} \]

### Step 2: Calculate the distance covered at a speed of 6 km/h in the same time.
Now that we have the time, we can find out how far the person would travel at a speed of 6 km/h in the same time of 3 hours. We use the formula for distance:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
Here, the speed is 6 km/h and the time is 3 hours.

\[ \text{Distance} = 6 \text{ km/h} \times 3 \text{ hours} = 18 \text{ km} \]

### Final Answer:
The person would cover a distance of **18 km** if he walks at a speed of 6 km/h for the same time.
