Q. Jovie is maintaining a camp fire. She has kept the fire steadily burning for 1010 hours with 1515 logs. She wants to know how many hours (h) she could have kept the fire going with 99 logs. She assumes all logs are the same.\newlineHow many hours can Jovie keep the fire going with 99 logs?\newlinehours
  1. Question Analysis: Question prompt: How many hours can Jovie keep the fire going with 99 logs?
  2. Rate Calculation: Determine the rate at which logs are used to keep the fire burning.\newlineWe have:\newlineTotal time the fire was burning = 1010 hours\newlineTotal logs used = 1515 logs\newlineRate of log usage = Total logs used / Total time\newlineRate of log usage = 1515 logs / 1010 hours\newlineRate of log usage = 1.51.5 logs per hour
  3. Time Calculation: Calculate the number of hours Jovie can keep the fire going with 99 logs.\newlineWe have:\newlineTotal logs available = 99 logs\newlineRate of log usage = 1.51.5 logs per hour\newlineTime (in hours) = Total logs available / Rate of log usage\newlineTime (in hours) = 99 logs / 1.51.5 logs per hour\newlineTime (in hours) = 66 hours
