## 3psilon Group Title p = ks and k is a constant s = nt and n is a constant How is p directly proportional to t? I don't get it one year ago one year ago

The answer is in the title I just don't understand why it's that

3. Arcturas

Just substitute for s in the first equation.

$p=k \times n \times t$ But k and n are constants. Therefore k * n is also a constant.
