B Correct answer
Explanation

Distance = 1 km = 1000 m. Speed = 8 m/s. Time = Distance / Speed = 1000 / 8 = 125 seconds.

AI explanation

First, convert the distance from kilometers to meters, making 1 km equal to 1000 meters. Using the Time formula (Time = Distance divided by Speed), divide 1000 meters by the speed of 8 m/s to get 125 seconds. The result is 125 sec.
