B Correct answer
Explanation

Speed = 25 m/s. Convert to km/h: 25 * (18/5) = 90 km/h. Distance = Speed * Time = 90 km/h * 8 h = 720 km.

AI explanation

First, convert the speed from metres per second to kilometres per hour by multiplying by 18/5, making the speed 90 km/hr. Using the formula distance equals speed multiplied by time, we multiply 90 km/hr by 8 hours. The total distance travelled by the car is 720 km.
