Answer:
6.
We know that Christine hiked Evergreen Trail twice and the Yellow River trail once. Also, that Brian hiked each of the three largest trails once. We are asked to find how many more miles Brian hiked than Christina.
7.
Before we answer the final question, we need to know how long these trails are.
8.
Christine
Evergreen: 4 3/4 × 2 = 6 3/4
Yellow River: 5 1/4 × 1 = 6 1/4
Brian
Hillcrest: 6 × 1 = 6
Yellow River: 5 1/4 × 1 = 6 1/4
Evergreen: 4 3/4 × 1 = 5 3/4
9.
Christine's total miles = 13
Brian's total miles = 19
To find the difference, we subtract the highest number by the smallest one.
So,
19 - 13 = 6
10.
This answer makes sense because Brian in fact did walk more miles than Christine and if you add 6 to 13 you get 19, or you can subtract 6 from 19 and get 13. This is a way to check that the answer is correct.
Hope this Helps!!
