Let's represent Jane's current age as J.
Tom's age is 3*J.
In ten years, Jane will be J+10 years old, and Tom will be 3*J+10.
The sum of their ages in ten years is J+10+3*J+10 = 4*J+20, which is equal to 80.
So, we have the equation 4*J+20=80.
Subtracting 20 from both sides gives 4*J=60.
Dividing both sides by 4 gives J=60/4=15 years old.
So, Tom is 3*15=<<3*15=45>>45 years old. Answer: \boxed{15, 45}.
