Problema Solution
The Present ages of Mark and Jonah are 15 and 24 years. X years ago, Jonah was twice as old as Mark. How many years ago was that?
Answer provided by our tutors
x years ago the age of Johan was: 24 - x
x years ago the age of Mark was: 15 - x
X years ago, Jonah was twice as old as Mark
24 - x = 2*(15 - x)
by solving the equation we find
x = 6 years
that was 6 years ago.
