students are planning a 3 day hike. The hike covers 18.5 kilometers. Students hike 0.28 of the total distance the first day. If they split the remaining distance equally between the second and third days, how far will they hike on day 3?

6.6 km

Step-by-step explanation:

The first day they cover 0.28 of the total 18.5 km hike, therefore, they cover: 0.28 * 16.5 = 5.18 km.

On each of the second and third days they cover half of what is left.

So what was left to cover from the first day is: the total 18.5 km minus 5.18 km. That is: 18.5 - 5.18 = 13.32 km.

Half of this distance is : 13.32 km divided by 2 which equals 6.66 km
