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.
Options:
Both plants are growing every day.
The bean plant Grows at a slower rate because it grows 2 inches while the strawberry plant grows 4 inches
The strawberry plant has grown 2 inches more than the bean plant
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
The correct answer is:
The bean plant grows at a slower rate because it grows 2 inches while the strawberry plant grows 4 inches.
To compare the two proportional relationships, we can look at how much each plant grows in a specific number of days.
The bean plant grows 2 inches in 2 days, which means it grows at a rate of 2 inches / 2 days = 1 inch per day.
The strawberry plant grows 4 inches in 5 days, which means it grows at a rate of 4 inches / 5 days = 0.8 inches per day.
Now, let's compare the options:
1. Both plants are growing every day: This is not a valid comparison as it does not provide any information about the growth rates of the plants.
2. The bean plant grows at a slower rate because it grows 2 inches while the strawberry plant grows 4 inches: This is not a valid comparison because we need to consider the time it took for each plant to grow the specified amount.
3. The strawberry plant has grown 2 inches more than the bean plant: This is not a valid comparison because it does not consider the time it took for each plant to grow.
4. 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 the correct comparison. The strawberry plant grows at a slower rate than the bean plant because it grows 0.8 inches per day while the bean plant grows 1 inch per day. The difference in growth rates is evident when comparing the amount of growth each plant achieves in the same number of days.
Therefore, the option "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" is the correct comparison.
To compare the two proportional relationships, we can look at the growth rate of each plant per day.
The bean plant grows 2 inches in 2 days, which means it grows at a rate of 1 inch per day.
The strawberry plant grows 4 inches in 5 days, which means it grows at a rate of 0.8 inches per day.
From this, we can see that the strawberry plant grows at a slower rate than the bean plant. Therefore, the correct option is:
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.
