Problem Statement

Prove that there exists a number α\alpha such that for any triangle ABCABC the inequality max⁡(hA,hB,hC)≤α⋅min⁡(mA,mB,mC) \max(h_A,h_B,h_C)\le \alpha\cdot\min(m_A,m_B,m_C) where hA,hB,hCh_A,h_B,h_C denote the lengths of the altitudes and mA,mB,mCm_A,m_B,m_C denote the lengths of the medians. Find the smallest possible value of α\alpha.
