To determine the speed of the car in kilometers per hour, we can use the relationship between distance, time, and speed. The formula for speed is:
[tex]\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \][/tex]
Given:
- The distance travelled is 600 kilometers.
- The time taken is 6 hours.
Let's substitute these values into the formula to find the speed:
[tex]\[ \text{Speed} = \frac{600 \text{ km}}{6 \text{ hours}} \][/tex]
Now, divide the distance by the time:
[tex]\[ \text{Speed} = 100 \text{ km/h} \][/tex]
Hence, the car travels at a speed of 100 kilometers per hour.
