In a marathon race, Chad is out in front, running due north at a speed of 3.92 m/s. John is 94 m behind him, running due north at a speed of 4.33 m/s. How long does it take for John to pass Chad
To find out how long it takes for John to pass Chad, we first need to determine the relative speed between them. Since they are both running due north, we can calculate the difference in their speeds by subtracting Chad's speed from John's speed:
Relative Speed = John's Speed - Chad's Speed
Relative Speed = 4.33 m/s - 3.92 m/s
Relative Speed = 0.41 m/s
Now, we can determine the time it takes for John to cover the 94 m distance and catch up to Chad. We can use the formula:
Time = Distance / Relative Speed
Time = 94 m / 0.41 m/s
Time ≈ 229.27 seconds
Therefore, it will take John approximately 229.27 seconds to pass Chad.
