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.

Answer 1

Answer:

$p = 4h$

Step-by-step explanation:

The equation of straight line is given by:

$y = mx$

where, m is the slope or rate of the line.

As per the statement:

Wangari plants 12 trees every 3 hours.

By definition of unit rate:

Unit rate per hour $= \frac{12}{3} = 4$ trees

⇒$m = 4$

We have to find an equation that relates the number of trees Wangari plants (p) and the time she spends planting them (h) in hours.

then;

$p=4h$
where, p represents the plant trees and the time she spends planting them in h hours
Therefore, $p=4h$   an equation that relates the number of trees Wangari plants (p) and the time she spends planting them (h) in hours.
