Question

Renata moved to her new home a few years ago. Back then, the young oak tree in her back yard was 1 9 0 centimeters tall. She measured it once a year and found that it grew at a constant rate. 3 years after she moved into the house, the tree was 2 7 4 centimeters tall.

Answer 1

It would grow 28 centimeters each year. 274-190=84 which is the difference from 3 years. You would then divide the 84 between three different years to get 28.
