D. The nervous system produces gametes
The difference between the speed of 100m race and 5000m race is larger because the difference between speed is more.
Explanation:
In the question given above we can see that in the first case the difference between both the distances that is 100m and 5000m is 4900m that is, (5000-100) . On the other hand the difference between the distance in the second case is (10000-5000) that is 5000m.
By comparing both the cases we can see that there is a difference of 100. Thus, we can say as the runner covers a distance of 100m it takes 10.44 m/sec and 5000m at 6.60m/sec , the speed difference is more.
