Question 1150261
Suppose that Bob is four years older than Alice. In two years, Bob will be twice Alice’s age. How old are Bob and Alice?
----------------
In two years, Bob will be twice Alice’s age.
--
No, he won't.
He will be twice as old as Alice, or his age will be twice Alice's age.
It's English.
==============
4 years difference and 2x --> 4 & 8.
Is that not obvious?
