The grass in Jamie's yard grew 16 centimeters in 10 days. It was growing at a constant rate.

How many days did it take the grass to grow 1 centimeter?

It's 1.6 you just have to divide 16 with 10

0.625

Step-by-step explanation:

As the excerpt says that the yard grew 16 centimeters in 10 days at a constant rate, you can use a rule of three to determine how many days it took to grow 1 cm:

10 days → 16 cm

x ← 1 cm

x = (1 cm*10 days) / 16 cm

x = 0.625 days

According to this, the answer is that it took 0.625 days for the grass to grow 1 centimeter.
