In 1 hour you'll have 4 cells so multiply that by 3 and you will have 12 cells in 3 hours
For this do 5/8-1/2!! in order to do this, find the common denominator. this one is 16, so do: 10/16-8/16, and simplify!

For example if it has been 2 months (l=1.25 times 2) the length would be 1.5 cm
M = ( (-6+4)/2, (3+-2)/2 )
M = (-1, 1/2)
