    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
        18.56 * t ^ 2 + 49.408 * t - 1132.768 ≥0         (1)

---

    From inequality(1)：
         t ≤ -9.255958 或  t ≥ 6.593889

---

    The final solution set is :
         t ≤ -9.255958 或  t ≥ 6.593889
