A bean plant grows 2 inches in 2 days, and a strawberry plant grows 4 inches in 5 days. Which plant grows at a slower rate? (find and compare unit rates).(1 point)

Question

The bean plant grows at a slower rate because it grows 2 inches and the strawberry plant grows 4 inches.
The bean plant grows at a slower rate because it grows 2 inches and the strawberry plant grows 4 inches.

The strawberry plant grows at a slower rate because it grows 0.8 inches per day, and the bean plant grows 1 inch per day.
The strawberry plant grows at a slower rate because it grows 0.8 inches per day, and the bean plant grows 1 inch per day.

The strawberry plant has grown 3 more inches than the bean plant.
The strawberry plant has grown 3 more inches than the bean plant.

Both plants are growing the same every day.

Answer 1

To determine which plant grows at a slower rate, we will calculate the growth rate (unit rate) for each plant in inches per day.

Bean Plant:

• Grows 2 inches in 2 days.
• Unit rate = \( \frac{2 \text{ inches}}{2 \text{ days}} = 1 \text{ inch per day} \)

Strawberry Plant:

• Grows 4 inches in 5 days.
• Unit rate = \( \frac{4 \text{ inches}}{5 \text{ days}} = 0.8 \text{ inches per day} \)

Now, comparing the two growth rates:

• Bean Plant: 1 inch per day
• Strawberry Plant: 0.8 inches per day

Since 0.8 inches per day (strawberry plant) is less than 1 inch per day (bean plant), the strawberry plant is growing at a slower rate.

Correct Response: The strawberry plant grows at a slower rate because it grows 0.8 inches per day, and the bean plant grows 1 inch per day.
