问题
On a trip, Marie drove 200 miles in 5 hours using gasoline that cost her $1.49 per gallon.
Column A Column B
Marie’s average speed for the trip in miles per hour Marie’s gas mileage for the trip in miles per gallon
选项
A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案
D
解析
某旅程中,Marie 5小时开出了200英里,汽车使用的汽油价格是每加仑1.49美元。
解:本题的正确答案为(D)。比较的左项为以英里每小时为单位,Marie旅程的平均速度;比较的右项为以英里每加仑为单位,Marie旅程的汽车里程。根据题目中所提供的信息可以求出Marie旅程的平均速度=200/5=40 mile/h;但是题目中未给出汽车所消耗的汽油数,因此无法计算每加仑汽油能行驶的英里数,从而也就无法判断两数的大小。
