Question

a student conducted an experiment on plant growth . Plat A was fed a different fertilizer than Plant b. before the experiment began, plant a measured 14 centimeters tall,and plant b measured 16 centimeters tall. at the end of the experiment plant a measured 18.2 centimeters tall and plant b measured 20 centimeters tall, which plant a or b grew at a greater rate?

Answer 1

Plant A grew at a greater rate.

Plant A grew a total of 18.2-14 = 4.2 cm.
Plant B grew a total of 20-16 = 4 cm.

Since they grew over the same time period, Plant A had a greater rate of growth.

Answer 2

Plan A grew at a greater rate.

Explanation:

Givens

• Plant A measured 14 centimeters tall.
• Plant B measured 16 centimeters tall.

After the experiment:

Plant A measured 18.2 centimeters tall.

Plant B measured 20 centimeters tall.

Now, let's see how much they actually grew:

Plant A: 18.2 - 14 = 4.2 cm.

Plant B: 20 - 16 = 4 cm.

As you can opbserve, plant A grew more centimeters than Plant B, specifically, 0.2 centimeters more.

Therefore, Plan A grew at a greater rate.
