Question

a single cell has become two cells after 90 minutes. How many cells will be there after 6 hours?

Answer 1

Hey mate,

In 90 min = 2

means in 1 hour = 2/1.5

so in 6 hours = 2/1.5×6

= 8 cells

hope this helps you out!

Answer 2

In 90 min = 2.                                         1 hour = 2/1.5

so, in 6 hours = 2/1.5×6

= 8 cells.                                                   Hence the answer is 8 cells
