Question

Sharon measures the growth of the new tree in her front yard. Her first measurement is when the tree is 1.0 m tall. She measures it every week. Each week it grows another 0.25m. If she continues to measure until it is twice as tall as her 175 cm height, how many weeks until she stops measuring the tree height?

Answer 1

3 Weeks; please read the explanation below.

Explanation:

I'd start by converting measurements. Make all meters into centimeters.

Then organize your info from the question:

• Her tree starts at 100 cm.
• That means her tree grows 25 cm each week.
• She is 175 cm tall

• Her tree has to grow 75 more cm to reach her height.

Now that you have your information, do the math:

to find how many weeks it will take until the tree grows 75 more cm you need to divide 75 by 25 (the growth rate).

75/25=3.

Therefore, it will take 3 weeks until Sharon's tree reaches her height and she stops measuring it. Hope this helps! :)
