Time (s) = 16.52 s
Length (cm) = 100 cm
This is for when a spring of 100 cm is sent to one end and than back. Each trip takes 16.52 seconds.

the amplitude is 50

Since you refer to a spring, I would guess that we're talking harmonic motion, and for the question to be even slightly interesting, what is wanted is the velocity amplitude. From the unclear wording I'd guess that the displacement amplitude X is either 50 cm or 100 cm from rest position, and that 16.52 sec is the half-cycle time. Then the radian frequency w = 2*pi/(2*16.52) = 0.19017 rad/sec. Velocity amplitude V = w*X = 9.5085 cm/s if X = 50 or 19.017 cm/s if X = 100. If 16.52 sec is the full-cycle time, then w, and consequently the V values, are doubled.

V = D/t = 100/16.52 = 6.053 cm/sec
Unless the whole trip is 200 cm? Then the answer is 200/16.52.

Speed=distance covered / time elapsed
200cm=0.2m (SI Unit)
therefore, speed=0.2/16.52=0.012m/s
or (in cm/s) 200/16.52=12.1cm/s
