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.

Step-by-step 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 :

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:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
