Question

A bean plant grows 2 inches in 2 days, and a strawberry plant grows 4 inches in 5 days. Compare the two proportional relationships. Assume each plant is growing at a constant rate.

a) Bean plant and strawberry plant have the same growth rate.

b) Bean plant has a faster growth rate.

c) Strawberry plant has a faster growth rate.

d) Growth rates cannot be compared.

Answer 1

The bean plant has a faster growth rate than the strawberry plant.

Step-by-step explanation:

The growth rates of the bean plant and the strawberry plant can be compared by calculating their rates of growth per day.

For the bean plant, it grows 2 inches in 2 days, so the rate of growth is 2 inches / 2 days = 1 inch per day.

For the strawberry plant, it grows 4 inches in 5 days, so the rate of growth is 4 inches / 5 days = 0.8 inches per day.

Comparing the two rates of growth, we can see that the bean plant has a faster growth rate than the strawberry plant.
