Question

A walker has travelled 9 km along a trail. If he has completed 80% of the trail, how much further does he still have to go?

Answer 1

Answer:

2.25 km to go

Step-by-step explanation:

In order to get this answer, you have to figure out how many km 10% is, 0.1125. Then multiply that by the remaining 20% because he already finished 80% of the trail. So, 0.1125 x 20 = 2.25.

Hope this helps! :)
