Answer: 6.25 meters/second
Explanation:
First convert 4 minutes to the standard SI unit of time (seconds)
4 min * (60 sec/1 min) = 250 seconds
Next recognize that average speed is found by dividing total distance (d) by time (t).
average speed = d/t
Substitute in known values and solve
average speed = 1500 m/250 sec = 6.25 meters/sec
