Question

How far is she from the end of the trail

Answer 1

The answer is A because Gemma was hiking for 2 1/2 a hour for 3 hours so u have to multiply 2.5 by 3 and that gonna equal 7.5 so u leave that alone and come back to it later so u get 11 3/8 minus 7.5 and it gonna equal 3 7/8 and I hope that helped you

Answer 2

Ok the total length of the trail is 11 3/8 miles
Gemma has walked 2 1/2 miles for 3 hours so 2 1/2 X 3 = 7 1/2
Now to find how far she has left until the trail ends is to just subtract 7 1/2 from 11 3/8 like so to find your answer 11 3/8 - 7 1/2 = 3 7/8 miles
Gemma has 3 7/8 miles until the trail ends 

Your answer would be A
