Quizplus · Accepted Answer

Since s varies directly as t^2, we can write the equation s = k*t^2, where k is the constant of variation. Given s = 320 when t = 8, we can find k by substituting these values into the equation: 320 = k*8^2, which simplifies to 320 = 64k. Solving for k gives k = 5. When t = 5, we substitute back into the equation to find s: s = 5*5^2 = 5*25 = 125.
