Question

The standard marathon distance is

42.2 km. If a marathon race starts and
finishes with one lap of a stadium which
is 400 m in length, what distance is run
on the road outside the stadium?


Hey Everybody,
Could someone please help me with this question. It's homework, due tomorrow.

Thank You!​

Answer 1

`41.8\ \text{km}`

Step-by-step 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* 10^3-400=41800\ \text{m}=41.8\ \text{km}`

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