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是四捨五入的意思,那這裡的答案應該是
285/12.4 and 294/11.5
還是這裡的rounded應該怎麼被理解呢？
