0.158 m/s

Step-by-step explanation:

Let the first runner be A.

Let the second runner be B.

Given the following data;

Total distance = 100m

Time A = 15.7 seconds

Time B = 16.1 seconds

To find their rate of speed;

For runner A;

Speed = 100/15.7

Speed A = 6.369

For runner B;

Speed B = 100/16.1

Speed B = 6.211 m/s

Next, we find the difference between their speed;

Difference = Speed A - Speed B

Difference = 6.369 - 6.211

Difference = 0.158 m/s.

Therefore, the first runner was faster than the second runner by 0.158 meters per seconds.

0.4 seconds faster / 0.158 m/s
