Final answer:
The distance covered by a car moving with a constant velocity of 25 m/s over 12 seconds is calculated using the formula distance = velocity × time, yielding a result of 300 meters.
Step-by-step explanation:
The question requires us to calculate the distance covered by a car moving with a constant velocity of 25 m/s over a time interval of 12 seconds. To find the distance, we can use the formula distance = velocity × time. Substituting the given values:
Distance = 25 m/s × 12 s = 300 m
Therefore, the car covers a distance of 300 meters in 12 seconds, which corresponds to option a. 300 m.
