Could you help me with this question, it was very easy but somehow didnt work.. I won't be able to sleep thinking on it.
A truck consumes 10 gallons gas per mile when driven in the city and 25 gallons gas per mile when driven in the highway. If it was driven 20 miles in the city and 30 miles in the highway, which of he following is the closest to its total average consumption?
a.16
b.18
c.20
D and E dont remeber but higher than 20.
I did (10*20 + 25*30)/30+20 = 19... but it was not an option!!!! the "closest" options were 18 and 20.. so which is the right one?
