A Correct answer
Explanation

Distance = 640 m. Time = 2 min 40 sec = 160 seconds. Speed = Distance / Time = 640 / 160 = 4 m/s.

AI explanation

The total time of travel is 2 minutes and 40 seconds, which equals 160 seconds. Using the formula for speed, speed equals distance divided by time. Dividing the distance of 640 m by the time of 160 seconds gives a speed of 4 m/s.
