Let the distance from S to T be x, the distance from T to U be 5x (since the ratio of ST:TU is 1:5), and the distance from U to V be 3x (since the ratio of TU:UV is 5:3).
Therefore, the total distance from S to V is x + 5x + 3x = 9x, which is equal to 27 (since SV = 27).
So, 9x = 27
x = 3
Therefore, the distance from S to T (ST) is x which is equal to 3.
Therefore, ST = 3.
