Final answer:
The car traveling at 30 metres per second will cover a total distance of 900 metres in 30 seconds, calculated using the formula distance equals speed multiplied by time.
Step-by-step explanation:
To calculate the distance travelled by a car moving with a speed of 30 metres per second over a period of 30 seconds, we use the formula for distance which is the product of speed and time.
The distance d is calculated as follows:
d = speed × time
Hence, substituting the given values:
d = 30 m/s × 30 s = 900 metres
Therefore, the car will travel a total distance of 900 metres in 30 seconds.
