conversations.value: Adam really wants to ride the biggest roller coaster at the park. You have to be 4 feet tall to ride it. Adam’s height is 40 inches and he grows 2 inches a year. How many years until he is tall enough to ride it?
  What is the solution?

conversations.value: Adam needs to grow 8 inches because 48 -40= 8
  It will take 4 years because 8/2=4
