Algebra Difficulty 1.8 Junior Find the answer

Jitka hiked a trail. After hiking 60% of the length of the trail, she had 8 km left to go. What is the length of the trail?

A number or a short expression. Spacing and $ signs are ignored.

Solution

After Jitka hiked 60% of the trail, 40% of the trail was left, which corresponds to 8 km. This means that 10% of the trail corresponds to 2 km. Therefore, the total length of the trail is 10×2=20 km 10 \times 2 = 20 \text{ km} .
