Question

The blue lake trail is 11 3/8 miles long. Gemma has hiked 2 1/3 miles each hour for 3 hours. How far is she from the end of the trail?

Answer 1

`4(3)/(8)miles`

Explanation:

Given that Gemma has hiked 2 1/3 mile each hour for a total of 3 hours, you can multiply her rate by her time to find the total distance:

d = rt or d = 2 1/3(3)

`2(1)/(3)=(7)/(3)`

Multiply:
`(7)/(3)*(3)/(1)=7miles`

Now, that the total length of the trail, 11 3/8 miles, and subtract the distance that Gemma has gone already:

11 3/8 - 7 =
`4(3)/(8)miles`
