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?

How many inches does Adam need to grow? ** Adam needs to grow 8 inches because 48 -40= <<48-40=8>>8
How many years will it take? ** It will take 4 years because 8/2=<<8/2=4>>4
