Sure, let's solve this step-by-step!

To find out how fast the car is going, we need to calculate its speed. The formula to calculate speed is:

[tex]\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \][/tex]

In this problem, the distance the car travels is 400 meters, and the time it takes is 20 seconds. Plugging these values into the formula gives:

[tex]\[ \text{Speed} = \frac{400 \text{ meters}}{20 \text{ seconds}} \][/tex]

Perform the division:

[tex]\[ \text{Speed} = 20 \text{ meters per second} \][/tex]

Therefore, the car is traveling at a speed of 20 meters per second.

So the correct answer is:

- 20 m/s
