今日练习题为综合推理题，题目如下：

The Quasi JX is a new car model. Under ideal driving conditions, the Quasi

JX's fuel economy is E kilometers per liter(E km/l) when its driving speed is

constant at S kilometers per hour (S km/h).

In terms of the variables S and E, select the expression that represents the

number of liters of fuel used in 1 hour of driving under ideal driving

conditions at a constant speed S, and select the expression that represents the

number of liters of fuel used in a 60 km drive under Ideal driving conditions at

a constant speed S. Make only two selections, one in each column.

1. Liters of fuel in 60 km = ?

A. S/E B. E/S C. 60/E D. 60/S E. E/60

2. Liters of fuel in 1 h = ?

A. S/E B. E/S C. 60/E D. 60/S E. E/60

正确答案：

C A

解题思路：

一升可以走E千米，即1 (L)=E (K);一小时可以走S千米，即1 (h)=S (K)

问题1：60千米耗油数量=60/E

问题2:1小时耗油量=S/E
