    Assignment:Find the solution set of inequality （9.8*t+161.6）*(2*t+17.04) ≥16*108*（t+17） .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 9.8 * t + 161.6 ) * ( 2 * t + 17.04 ) ≥16 * 108 * ( t + 17 )         (1)

---

    From inequality(1)：
         t ≤ -16.955447 或  t ≥ 80.108916

---

    The final solution set is :
         t ≤ -16.955447 或  t ≥ 80.108916
