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.
