Answer :

Given :

Rochelle is competing in a marathon.

She knows that once she runs 14.7 km she will have completed 35% of the marathon.

To Find :

Total length of the marathon.

Solution :

Let, total distance of the marathon is x km.

So, 35% of x is 14.7 .

In mathematics :

[tex]14.7 = x\times \dfrac{35}{100}\\\\x = \dfrac{14.7\times 100}{35}\\\\x = 42\ km[/tex]

Therefore, total length of the marathon is 42 km.
