Teresa is maintaining a camp fire. she can keep the fire burning for 4 hours with 6 logs. she wants to know how many logs she needs to keep the fire burning for 18 hours. she assumes all logs are the same.

Teresa will need 27 logs to keep the fire going for 18 hours.

Step-by-step explanation:

Teresa can keep the firing going for four hours with six logs. We can therefore determine the amount of logs is needed per hour:

amount of logs needed per hour so we need 1.5 logs/hour to keep the fire going.

If Teresa wants to keep the fire going for 18 hours we can determine this by multiply the 18 hours by the logs per hour rate:

Logs needed for 18 hours of burning a camp fire

Therefore she will need 27 logs to keep the fire going for 18 hours.
