Answer 1

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 :

`14.7 = x* (35)/(100)\\\\x = (14.7* 100)/(35)\\\\x = 42\ km`

Therefore, total length of the marathon is 42 km.
