Eugene can advance 6m in 8 sec, so 12m in 16 sec.

Then he falls back 2m after 1 sec rest.
Nett, he advances 10m in 17 sec.

It will therefore take him 9 x 17 = 153 sec to reach the 90m mark.

From the 90m mark, he will need another 12m (ie. 16 sec) to reach point B.
153 + 16 = 169 seconds

Earlier post was incorrect. Sorry.


White Triangles: 1+2+3+4…+100= 5050
Black Triangles: 1+2+3+4…+99= 4950 ( Gauss Theorem )
Total: 4950 + 5050 = 10000
4950/10000 = 99/200

Hence, answer is 2.
