Final answer:
The given information does not provide enough data to determine the amount of time it would take for the CO2 level to reach 5% in the atmosphere.
Step-by-step explanation:
The question is asking how long it will take for the CO2 level in the atmosphere to reach 5% after the failure of a spacecraft's scrubbing system. The given information does not provide enough data to determine the amount of time it would take for the CO2 level to reach 5% in the atmosphere.
In order to answer this question, we need to know the normal daily rate of CO2 production. However, this information is not provided in the given text. Therefore, it is not possible to determine the amount of time it would take for the CO2 level to reach 5% based on the given information.
