B Correct answer
Explanation

Distance = 750 m = 0.75 km. Time = 2 min 30 sec = 150 sec = 150/3600 hours = 1/24 hours. Speed = Distance / Time = 0.75 / (1/24) = 0.75 * 24 = 18 km/hr.

AI explanation

First, convert the given time of 2 minutes and 30 seconds into hours by dividing 150 seconds by 3600, which equals 1 divided by 24 hours. Use the formula Speed equals Distance divided by Time, substituting 750 meters as 0.75 kilometers. The speed is 0.75 multiplied by 24, which equals 18 km/hr.
