Formula helpI've got this equation for blood alcohol content, and I need to find the BAC at certain times. BAC equation: B = (A/rW) * 100 - V t B where B = Bac, A is amount of alcohol in grams, r = 0.7, W is mass in grams, V is 0.015 and t is time since drinking. I have to find bac with mass 75000 grams (75kgs), 50 grams of alcohol after 5 hours. I subbed it all in and the answer is 0.02, which is fine. My question is, I need to find how long will it take for the BAC to be below 0.05 in the above question. Is revision question, so please help me! Thank you. |

Re: Formula helpWould it just be setting b = 0.05 and solving for t? I tried that and got 2.4 is that the right answer? |

Re: Formula helpLordy, lordy...can you post your problem again, paying attention to Capitals and lowercase; like, A and a would be 2 DIFFERENT variables :idea: |

Presumably, BAC means "blood alcohol concentration". |
