Final answer:
To find the time it took the student to walk 250 meters at 2.0 meters per second, we divide the distance by the speed, resulting in 125 seconds.
Step-by-step explanation:
A student walks a distance of 250 m at a speed of 2.0 m/s. To calculate how long it took in seconds, we can use the formula for time, which is the distance traveled divided by the speed. Therefore, the time taken (t) is:
t = distance / speed
t = 250 m / 2.0 m/s
t = 125 seconds
Thus, it took the student 125 seconds to walk a distance of 250 m at a speed of 2.0 m/s.
