Answer: A.
Another way to solve by factoring 1/4.

![= [\dfrac{1}{4}(A + B)]^2](https://tex.z-dn.net/?f=%20%3D%20%5B%5Cdfrac%7B1%7D%7B4%7D%28A%20%2B%20B%29%5D%5E2%20)




Answer:
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 1.26.....m, 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)
Simple 10, 20, 30, 40, 50, 60, 70, and so on
