She could have hiked one 2 mile trail and one 1 mile trail or she could’ve hiked one 2.5 mile trail and another 0.5 mile trail
Hi there!

To find other possible combinations, we can see which other numbers add up to 3:

1 + 2 = 3
Andrea could have hiked one 1 mile trail and one 2 mile trail. 

2 1/2 + 1/2 = 3
Andrea could have hiked a 2 1/2 mile trail and a 1/2 mile trail.

Hope this helps!
