7 Ray’s school is 1.7 miles from his house. He walks to and from school every day.
How many miles does he walk each day? Show all your work.

To find out how many miles Ray walks each day, we need to consider the distance to school and back home. Since Ray walks 1.7 miles to school and then the same distance back home, we can calculate the total distance as follows:

Distance to school: 1.7 miles
Distance back home: 1.7 miles

Total distance walked in one day = Distance to school + Distance back home
Total distance walked in one day = 1.7 miles + 1.7 miles
Total distance walked in one day = 3.4 miles

So, Ray walks a total of 3.4 miles each day.
