Practice objective / multiple choice question 26 from the 2024 Igcse Model Questions Vol1 Biology examination.
A bacterial culture initially contains \(2.0\times10^{6}\) cells. Under optimal conditions it grows to \(1.6\times10^{8}\) cells in 4 h, while under sub‑optimal conditions it reaches \(5.0\times10^{7}\) cells in 6 h. Assuming exponential growth, calculate the ratio of the generation time under optimal conditions to that under sub‑optimal conditions. Give your answer to two decimal places.
