A car travels a distance of 15 km in 20 minute. Find the speed of the car in `ms^(-1)`

Explanation

To find the speed of the car in meters per second (m/s), we will follow these steps:

### Step 1: Convert Distance from Kilometers to Meters
The distance traveled by the car is given as 15 kilometers. We need to convert this distance into meters since the speed needs to be calculated in m/s.

\[ \text{Distance in meters} = 15 \text{ km} \times 1000 \text{ m/km} = 15000 \text{ m} \]
