The below image will help to understand the graph in a xy-plane.
\(A = 1.8 (Race_1)+2.8 (Race_2) \approx 4.6\)
\(E = 4 (Race_1)+2 (Race_2) = 6\)
Ans A

Why not C then? Isnt that the highest total?

You are correct, C does have the highest total. However we are trying to find the fastest cyclists, meaning the one with the lowest time.

Hopefully, this clears it up!

i think for this type of question, an efficient approach would be to think from a Matrix (Quadrants) perspective. Since we are asked for the combined minimum time of the cyclist, cyclist whose times falls in 3 quadrant will be the minumim.

for instance, Quadrant 1 (H, H); Quadrant II, (H, L), Quadrant III (L, L), Quadrant IV (L, H). L and H are low and High respectively.

As the combined times of cyclist A lies on 3 Quardrant, he is the fastest.
