Question

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

a. (p = 4h)
b. (p = 3h)
c. (p = 12h)
d. (p = frac{h}{4})

Answer 1

The equation that relates the number of trees Wangari plants (p) and the time she spends planting them in hours (h) is p = 4h.

Step-by-step explanation:

The equation that relates the number of trees Wangari plants (p) and the time she spends planting them in hours (h) is p = 4h.

Wangari plants trees at a constant rate of 12 trees every 3 hours. So, in 3 hours, she plants 12 trees. This can be expressed as: p = 12. To find the equation in terms of h, we can divide both sides of the equation by 3 (since 3 hours is the unit of time mentioned in the question). This gives us: p/3 = 12/3, which simplifies to: p/3 = 4. Multiplying both sides of the equation by 3 gives us the final equation: p = 4h.

Therefore, the correct equation that relates the number of trees Wangari plants and the time she spends planting them in hours is p = 4h.
