If u pour a cup of coffee that is 200 degress F, and set it on a desk in a room that is 68 degrees F, & 10 minutes later it is 145 degres F, what tempetrature will it be 15 min after u originally poured it?

Thank you for the opportunity to help you with your question!

if you lost 55 degrees in 10 min you would loose 5.5 degrees in 1 min then you multiply by 15. 15* 5.5 = 82.5 degrees then you subtract from 200. 200-82.5 = 117.5 degrees in 15 min <--------Answer
