 | Question 576189:  Two gasoline distributors, A and B, are 367 km apart on a highway.A charges $1.80/L and B charges $1.68/L. Each charges 0.16˘/L per kilometre for delivery. Where on Interstate 80 is the cost to the customer the same? Sir,
 I didn't get what is meant by "Interstate 80 is the cost to the customer the same".Even then I tried to solve as follows.
 (1.80*0.16)*x=80
 (1.68*0.16)*y=80
 giving x=277.77 and y=297
 I think I have messed it up and cant find the solution.It will be kind of you if you you can help me out in this regards.
