Question

Janet can make 3/5 of a neckalce in 20 minutes. At this rate how many necklaces, to the nearest tenth of a necklace, can Janet make in 1 hour?

Answer 1

Janet can make approximately 1.8 necklaces in 1 hour.

Step-by-step explanation:

To find out how many necklaces Janet can make in 1 hour, we need to determine how many intervals of 3/5 of a necklace fit into 1 hour. To do this, we need to convert 1 hour to minutes. Since 1 hour is equal to 60 minutes, we can set up a ratio:

3/5 of a necklace / 20 minutes = x necklaces / 60 minutes

We can cross multiply and solve for x:

3/5 * 60 = 20x

x = (3/5) * (60/20)

x = 9/5

So, Janet can make approximately 1.8 necklaces in 1 hour.
