6 per hour

Step-by-step explanation:you would divide 15 by 2 and 1/2

Answer 2

Part A:

The number of plants Nestor will pot in 1 hour is:

6 plants.

Part B:

The number of plants that he will be able to pot in 3 1/2 hour is:

21 plants.

Explanation:

Part A:

It is given that:

Nestor takes 2 1/2 hours to pot 15 plants.

i.e.

It takes him 5/2 hours to pot 15 plants.

Hence, In 1 hour he will pot:

`(15)/((5)/(2))\ \text{plants}\\\\=(15* 2)/(5)\ \text{plants}\\\\=6\ \text{plants}`

Part B:

Also, if he continues to work at the same rate then the number of plants he will pot in 3 1/2 hour is:

( We know that:

`3(1)/(2)=(3* 2+1)/(2)\\\\i.e.\\\\3(1)/(2)=(7)/(2)\ \text{hour}` )

Hence, the number of plants that will be potted in 7/2 hours is:

`=6* (7)/(2)\\\\=21\ \text{plants}`
