find most economical speed

Let C be the total cost of running the bus per hour and V be the speed in km/hr,

C = [Rs 48 / (20 km/hr)2]V2 + Rs. 180

C = 0.12V2 + 180.

As we can see the most economical speed is ZERO, since then only we get minimum expenses and those are the fixed charges.

We would request you to clarify / provide additional details so that we may answer this to the best of the ability.
