Emek and Luna were hiking through a canyon when a fallen boulder blocked the trail to their campsite. Two paths went around it. Using their measuring tool, they found that the upper path had sections of 46 meters and 38 meters. The lower path had sections of 57 meters and 31 meters. Emek added the upper distances and got 84 meters. Luna found that the lower path was 88 meters. Since 84 meters was shorter, they chose the upper path and reached camp before sunset.

Hint
Both sections are part of the same path, so combine their lengths.
The upper path has sections of 46 meters and 38 meters. Which calculation gives the total length of the upper path?
46 - 38 = 8 meters46 + 38 = 84 meters46 + 31 = 77 meters57 + 38 = 95 metersCorrect! Adding the two sections gives a total length of 84 meters.
Add the lengths of the two sections that make up the upper path.

Hint
Find the difference between 88 meters and 84 meters.
The upper path is 84 meters long, and the lower path is 88 meters long. How many meters shorter is the upper path?
Correct! The upper path is 4 meters shorter.
Subtract the shorter distance, 84 meters, from the longer distance, 88 meters.

Hint
Compare the three distances: 84 meters, 88 meters, and 86 meters.
Suppose a third path around the boulder is 86 meters long. Which path would be the shortest?
The lower path at 88 metersThe third path at 86 metersThe upper path at 84 metersAll three paths are the same lengthCorrect! Of the three distances, 84 meters is the shortest.
Compare 84, 88, and 86. The path with the smallest distance is the shortest.
