My friend is an athlete,he is a marathon runner (but he had never won),he says always:

well,if they let me start running 14 Minutes before the others, I`ll win the race even if the best runner in the world( who needs 2 hours ,3 minutes and 59 seconds to complete the marathon ),was in the race.

At which speed (Km/h)(as an average) can my friend run? if he can win( under this condition) the world champion in one second.

Note:The marathon is defined as 42.195 km

18.346 km/h or 11.4 mph

Roughly 14 km/h with about a minute of thought, probably wrong.

Here we go.

I came to a result of 18,35 km/h so i guess EE gets the credit for solving this!

My brains on rot, guess i'm missing something, or else

Fastest runner needs 4+120 minutes. Your buddy needs 124+14 minutes. 42.195km/138 min = 18.345 km/h

18.3457 km/hr

Winning by 1 second the World champion
