Answer:

Step-by-step 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)

Multiply: 
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 = 
301,931
^ This is the 100,000 place.
We round down because the number next to it is 0.
So we round do 300,000
