Final answer:
Aaron runs approximately 6.758 meters in one second at a constant speed, calculated by dividing the distance he runs by the time (39.86 m ÷ 5.9 s).
Step-by-step explanation:
If Aaron runs 39.86 meters in 5.9 seconds at a constant speed, to find out how far he runs in one second, we must calculate his speed. Speed is the distance traveled divided by the time it takes to travel that distance.
Using the formula speed = distance ÷ time, we get:
Speed = 39.86 meters ÷ 5.9 seconds
= 6.758 meters per second
Therefore, Aaron runs approximately 6.758 meters in one second if he maintains a constant speed.
