A bean plant grows 2 inches in 2 days. A strawberry plant grows 4 inches in 5 days. Compare the two proportional relationships. Assume each plant is growing at a constant rate.
A The strawberry plant grows at a slower rate because it grows 0.8 inches per day while the bean plant grows 1 inch per day.
B Both plants are growing every day.
C The strawberry plant has grown 2 inches more than the bean plant.
D The bean plant grows at a slower rate because it grows 2 inches while the strawberry plant grows 4 inches.
D The bean plant grows at a slower rate because it grows 2 inches while the strawberry plant grows 4 inches.
The correct answer is A. The strawberry plant grows at a slower rate because it grows 0.8 inches per day while the bean plant grows 1 inch per day.
To compare the two proportional relationships, we need to calculate the rate at which each plant grows.
For the bean plant, it grows 2 inches in 2 days, so its growth rate is 2 inches ÷ 2 days = 1 inch per day.
For the strawberry plant, it grows 4 inches in 5 days, so its growth rate is 4 inches ÷ 5 days = 0.8 inches per day.
Now, let's look at the answer choices:
A) The strawberry plant grows at a slower rate because it grows 0.8 inches per day while the bean plant grows 1 inch per day.
This is correct. The bean plant grows at a faster rate of 1 inch per day compared to the strawberry plant's growth rate of 0.8 inches per day.
B) Both plants are growing every day.
This statement is true, but it doesn't provide a comparison between the two plants' growth rates.
C) The strawberry plant has grown 2 inches more than the bean plant.
This statement is not accurate because we have not compared the total growth of the two plants. We are looking to compare their growth rates.
D) The bean plant grows at a slower rate because it grows 2 inches while the strawberry plant grows 4 inches.
This statement is incorrect. The growth rate is determined by the amount of growth per unit of time, not the total growth. In this case, the strawberry plant grows at a slower rate of 0.8 inches per day compared to the bean plant's growth rate of 1 inch per day.
Therefore, the correct answer is A. The strawberry plant grows at a slower rate because it grows 0.8 inches per day while the bean plant grows 1 inch per day.
