Answer:
[tex]p=4h[/tex]
Step-by-step explanation:
Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.
We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.
Let us find number of trees planted in 1 hour by dividing 12 by 3.
[tex]\text{Number of trees planted in 1 hour}=\frac{12\text{ plants}}{3\text{ hour}}[/tex]
[tex]\text{Number of trees planted in 1 hour}=4\frac{\text{ plants}}{\text{ hour}}[/tex]
We can represent this information as: [tex]p=4h[/tex]
Therefore, the equation [tex]p=4h[/tex] relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.
