Question

Wangari plants trees at a constant rate of 12 trees every 3 hours. Write a equation that relates p, the number of trees Wangari plants, and h, the time she spends planting them in hours.

Answer 1

4h=p

Explanation:

This is the answer because if both the number of trees and hours is divided by three, you get 4 trees per hour. So it's 4 times (h) equals total amount of trees planted.

Answer 2

Answer:
`p=4h`

Explanation:

The given statement: Wangari plants trees at a constant rate of 12 trees every 3 hours.

Using unitary method, the number of tree planted by Wangari in every hour :

`=(12)/(3)=4`

i.e. Wangari plants trees at a constant rate of 4 trees every hour.

Let the number of trees planted by Wangari be 'p'and h, the time she spends planting them in hours.

Then, equation that relates p and h will be:

`p=4h`
