I came across an Integrated Reasoning question from GMAT prep software. It goes something like the following:
" QUASI JX is car model, it's fuel economy is E km per litre ( E km ) when its driving speed is constant at S km per hour ( S km )
_ _
L H
What is the no. of fuel used in 1 hr of driving at constant speed S? "
How do I answer this question? I dont get quite a few things in this question. Firstly, what is implied by " fuel economy " ? I just dont get it. Shouldnt it just say distance? The second thing is what concept is being used here? Whats the starting point to solve this question? Whats the basic concept that I need to derive from this question. Also, the expression that I have bolded in the question seem confusing. For instance in the first one, is E meant to multiply by L or is it supposed to be Ekm/L?
Please how can I understand this better?In the solution provided it says, " the car required 1/E litres of fuel to travel 1 km "
how is that solution reached??
