Answer:
5 3/5
Step-by-step explanation:
The wording "combined laps" means you want the sum of the two numbers of laps. You can add their integer parts and their fractional parts.
... (3 2/5) + (2 1/5) = (3 + 2) + (2/5 + 1/5)
... = 5 + 3/5 = 5 3/5
_____
The fractions add to less than 1, so no additional work is necessary.
