C Correct answer
Explanation

Speed = 15 kmph = 15 * (5/18) m/s = 75/18 = 25/6 m/s. Time = Distance / Speed = 750 / (25/6) = 750 * 6 / 25 = 30 * 6 = 180 seconds. 180 seconds = 3 minutes.

AI explanation

Using the Time formula (Time = Distance divided by Speed), we divide 0.75 km by 15 kmph to get 0.05 hours. Multiplying 0.05 hours by 60 converts the time to 3 minutes. The result is 3 min.
