One metric hour equals 100/60 = 1.67 normal hours.
One metric minute equals 100/3600 = 0.027 normal hours. 
One metric second equals 0.027/100 = 0.00027 normal hours. 
Multiplying this by 3600 to convert from hours to seconds, we get 0.00027 x 3600 = 0.864 normal seconds. Therefore, the answer is B.
