Ismael Villarreal · Answer 1

Mom is 30 years old when Serena is 10 because 10 x 3 = 30.

They are 20 years apart. [This is key]

Half (.5) of mom's age will be = to Serena's age.

Therefore, when mom is 40 years old, Serena is 20 years old.

We can see that half of 40 = 20.

Hope this makes sense!
