Answer:
When p=18, t=6
Step-by-step explanation:
If p and t are directly proportional, then:
p = k.t
Where k is the constant of proportionality.
We are given an initial condition: when p=12, then t=4. Substituting in the equation:
12 = k.4
Solving for k
k = 12/4 =3
The equation is:
p = 3t
Now we are required to find the value of t when p=18:
18 = 3t
Solving for t:
t = 18/3 = 6
t = 6
Thus, when p=18, t=6
