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
