The speed of light IN A VACUUM is ≈3E8 m/s. The OP specifically said that he was talking about "in a medium".First off, the speed of light is ≈3.00X10E8 m/s, I'm not sure where you got that number (X10E-8?).
60cm = 0.06m
So 3.00X10E8 m/s ÷ 0.06 m = 5e9 / s
Invert it. S / 5e9 = 2e-10 S or 200 nanoseconds.
