To find the number of days when Juanita will run and swim again on the same day, we need to find the least common multiple (LCM) of 3 and 5.

First, let's find the multiples of 3: 3, 6, 9, 12, 15, 18, ...

Next, let's find the multiples of 5: 5, 10, 15, 20, 25, 30, ...

We can see that the first common multiple of 3 and 5 is 15. Therefore, Juanita will run and swim again on the same day in 15 days.

Alternatively, we can use the formula to calculate the LCM of two numbers:

LCM(a, b) = (a * b) / GCD(a, b)

Where GCD(a, b) is the greatest common divisor of a and b.

GCD(3, 5) = 1 (since 3 and 5 are prime numbers)

Therefore, LCM(3, 5) = (3 * 5) / 1 = 15. So, Juanita will run and swim again on the same day in 15 days.
