Question

The standard marathon distance is

Answer 1

Answer:

$41.8\ \text{km}$

Explanation:

Total distance of one lap of the marathon = 42.2 km

Distance of the lap that is inside the stadium = 400 m

The distance that is run outside the stadium is the difference between the two distances

$42.2\times 10^3-400=41800\ \text{m}=41.8\ \text{km}$

The distance that is run on the road outside is $41.8\ \text{km}$..
