A Certain Strain of Bacteria Divides Every Three Hours $t = 3 \frac { \log ( N / 50 ) } { \log 2 }$

Short Answer

A certain strain of bacteria divides every three hours. If a colony is started with 50 bacteria, then the time t (in hours) required for the colony to grow to N bacteria is given by $t = 3 \frac { \log ( N / 50 ) } { \log 2 }$ Find the time required for the colony to grow to five million bacteria.
