Answer:
17cm/year is the rate of change in length per year.
Step-by-step explanation:
Since the rate of change in the length per year is same every year , we can find out the rate of change by dividing total change in length by the number of years that was taken for that change in length to occurs. According to the question, 255 ÷ 15 = 17 cm/year
