Comparing Plant Growth Rates

The video tutorial compares the growth rates of two plants owned by Hannah and Martine. Hannah's plant grows at 2 centimeters per week, while Martine's grows at 3 millimeters per day. To accurately compare the growth rates, the video demonstrates converting Martine's growth rate to centimeters per week, resulting in 2.1 centimeters per week. The tutorial concludes that Martine's plant grows slightly faster than Hannah's when using consistent units.

What is the growth rate of Hannah's plant?

• Two millimeters per day

• Two centimeters per week

• Three millimeters per day

• Three centimeters per week

What is the growth rate of Martine's plant?

• Three millimeters per day

• Two centimeters per week

• Two millimeters per day

• Three centimeters per week

Why is it incorrect to compare the numbers 3 and 2 directly in this context?

• Because they are measured at different times

• Because the units of measurement are different

• Because they are different types of plants

• Because one is a decimal and the other is a whole number

What is the first step in converting Martine's growth rate to centimeters per week?

• Convert weeks to days

• Convert millimeters to centimeters

• Convert centimeters to millimeters

• Convert days to weeks

How many millimeters does Martine's plant grow in a week?

• 21 millimeters

• 28 millimeters

• 35 millimeters

• 14 millimeters

How do you convert millimeters to centimeters?

• Divide by 100

• Multiply by 100

• Divide by 10

• Multiply by 10

What is Martine's plant growth rate in centimeters per week?

• 2.5 centimeters

• 1.5 centimeters

• 2.0 centimeters

• 2.1 centimeters

Which plant grows faster when comparing the same units?

• Martine's plant

• Hannah's plant

• Both grow at the same rate

• Cannot be determined

What is the final conclusion about the growth rates of the plants?

• Both plants grow at the same rate

• Martine's plant grows faster

• Neither plant grows

• Hannah's plant grows faster

What is the importance of converting units in this problem?

• To make the numbers look bigger

• To change the growth rates

• To confuse the reader

• To ensure a fair comparison
