Hiking trail

The newly built hiking trail leads 25% through the field, 3/8 of the trail leads through the forest and the remaining 9 km along the river. How long is the train?

Correct answer:

x =  24 km

Step-by-step explanation:


0.25 x + 3/8·x + 9 =x

0.25·x + 3/8·x + 9 =x

3x = 72


x = 72/3 = 24

x = 24
