标题[Q. ] rounded to the nearest
时间Fri Feb 3 21:37:25 2017
on a recent trip, cindy drove her car 290 miles,
rounded to the nearest 10 miles, and used 12 gallons of gasoline,
rounded to the nearest gallon. the actual number of miles per
gallon that cindy's car got on this trip must have been between.
答案 285/12.5 and 295/ 11.5
如果rounded是四舍五入的意思,那这里的答案应该是
285/12.4 and 294/11.5
还是这里的rounded应该怎麽被理解呢？
