Answer:
6 cells
Step-by-step explanation:
Cell A = 1 hour to complete cycle and produce 2 cells
Number of cycles completed on 6 hours = 6 cycles
Number of cell produced = 2 * number of completed cycles = 2 * 6 = 12 cells
Cell B = 2 hours to complete a cycle ; 2 cells produced per cycle
Number of cells produced after 6 hours :
Number of cycles in 6 hours = 6/2 = 3 cycles
Number of cells produced = 3 * 2 = 6 cells
Difference in cells produced : (12 - 6) = 6 cells
