Final answer:
After calculations, Elijah's family walks a total distance of 6.825 km, while Rani's family walks 6.675 km, making Elijah's family the one who walks farther by 0.15 km.
Step-by-step explanation:
The question asks us to compare the distances walked by Rani's family and Elijah's family, using the given lengths of three trails: Lower Trail, Ridge Trail, and Panther Trail. We must calculate the total distance each family walked and then compare the two distances. Rani's family walks the Lower Trail three times, so we multiply the length of the Lower Trail by three. Elijah's family walks the Ridge Trail once and the Panther Trail once, so we add the lengths of those two trails together for the total distance.
Rani's Family: Lower Trail walked 3 times = 2.225 km × 3 = 6.675 km
Elijah's Family: Ridge Trail walked 1 time = 3.45 km
Panther Trail walked 1 time = 3.375 km
Total for Elijah's Family = 3.45 km + 3.375 km = 6.825 km
Comparing the two totals, we can see that Elijah's family walked a slightly greater distance than Rani's family:
6.825 km (Elijah's Family) > 6.675 km (Rani's Family)
The difference between the distances they walked is 6.825 km - 6.675 km = 0.15 km.
Therefore, Elijah's family walks farther by 0.15 km.
Complete question:
Rani's family walks the lower trail three times. Elijah's family walks the ridge trail one time and the panther trail one time. Whose family walks farther? How much farther does that family walk? Show your work.
