5,还有一个我一开始算错又改回来的,热得快让温度升高0.5摄氏度每分钟,然后问说每小时升高多少华氏度 题目给了个换算比例是90度华氏等于50度摄氏度 我一开始算反了,把比例弄颠倒了,大家注意以下到时别反了,算出来是54 if the temprature is increased by 0.5C/min, then it will increase 30C per hour, according to C=(F-32)* (5/9), F=86. Are you sure it is 54? Thanks, Now I know the problem. This question is asking the change rate, is not absolute temperature. So the change rate of C is 5/9 of change rate of F, So the Answer should be 54.
