Dawn walked 3/10 miles to the park. The park has a path that is 2/5 miles long. She walked around the path 4 times. Then she walked back home. What is the total distance Dawn walked?

(3/10) + 4 (2/5) + (3/10)

2 (3/10) + (8/5)

(6/10) + (8/5)

(6/10) + (16/10)

(6+16) / 10

22/10

(20+2) / 10

2 2/10

2 1/5 miles

2/5 times 4 is equal to blank miles because 2 times 4 is 8 and 8/5 reduces to 1 and 3/5 or 6/10.

3/10 times 2 would be 6/10 because it would be to and from home

add the two 1 6/10 + 6/10 = 1 12/10 which equals 2 and 2/10 or 1/5

Answer: 2 1/5 miles.
