C. 55s

Step-by-step explanation:

I'll refer to Wyndham as W and Michael as M.

Also, we will be assuming constant speed for both runners.

So, first of all, W ran with a speed of 8m/s;

400m/50s = 8 m/s

M ran with speed 9.2635 m/s;

400m/43.18s = 9.26 m/s

The difference is 1.26 m/s, meaning every second, the distance between M and W would increase by 1.26m, starting from 0 at the start line;

9.26... - 8 = 1.26

So, to find the desired distance, we simply multiply 1.26... by 43.18;

1.26... × 43.18 = 54.560

(Rounded up to 55s)
