I am 15 y.o. My dad is three times older than me and my mom is 5 years younger than my dad. How old is my mom?

Let's solve this step by step:

1. **Age of your dad**: 
   Your dad is three times older than you. If you are 15 years old, then your dad's age is:
   \[
   \text{Dad's age} = 3 \times 15 = 45 \text{ years old}
   \]

2. **Age of your mom**: 
   Your mom is 5 years younger than your dad, so her age is:
   \[
   \text{Mom's age} = 45 - 5 = 40 \text{ years old}
   \]

So, your mom is 40 years old.
