To find the total time it takes for the sprinter to run 100 meters at a speed of 7 meters per second, we can use the formula:
Time = Distance / Speed
Time = 100 meters / 7 meters per second
Time = 14.29 seconds
Next, we can find the time it takes for the sprinter to cool down by running 100 meters at a speed of 3.5 meters per second:
Time = 100 meters / 3.5 meters per second
Time = 28.57 seconds
Therefore, the sprinter takes a total of 14.29 + 28.57 = 42.86 seconds to complete both the sprint and cool-down.
A sprinter runs 100 at a speed of 7 meters per second. Then she cold down by running 100 meters at 3.5 meters per second.
