Speed = Distance / Time
Given:
Distance = 1500 meters
Time = 4.00 minutes =4*60=240 seconds
Speed = 1500 / 240 = 6.25 m/s
Thus, the man's speed is 6.25 meters per second.

To calculate the speed of the man in meters per second, we need to convert the time from minutes to seconds and then divide the distance by the time.

Given:
Distance = 1500 meters
Time = 4.00 minutes

1 minute is equal to 60 seconds. So, we have:
Time = 4.00 minutes × 60 seconds/minute
Time = 240 seconds

Now, we can calculate the speed:
Speed = Distance / Time
Speed = 1500 meters / 240 seconds

Speed 6.25 meters/second

Therefore, the speed of the man is approximately 6.25 meters per second.
