Melissa ran 11 29/60 miles in all.

Explanation:

To solve this problem, first, you need to find a common denominator, also known as a least common multiple (LCM). The LCM of 3, 4, and 5 is 60, so you know you need to change all of the fractions to a denominator of 60.

  • 2/5 is equal to 24/60
  • 3/4 is 45/60
  • 1/3 is 20/60

Add these up and you get 89/60. Change this into a mixed number and you get 1 29/60. Then you add the mixed numbers and get 6+2+2, which is 10.

10 + 1 29/60 = 11/60

so this is your final answer.
