Daria walked 3 and 7/10 miles in all.
To solve, first add the whole numbers. (1+2 = 3)
Next, make the fractions have the same base. (Convert 2/5 to 4/10)
Now, add the fractions. (4/10 + 3/10 = 7/10)
Finally, add the sum of the fractions to the sum of the whole numbers. (3 +7/10 = 3 and 7/10)
Your answer is 3 and 7/10. Or 37/10.
