How is the vehicle operating cost related to the time for unit distance?

• A. \(T=a+\frac{(b-c)}{speed}\)
• B. \(T=a-\frac{(b-c)}{speed}\) c) \(T=a+\frac{(b+c)}{speed}\) d) \(T=a-\frac{(b+
• C. }{speed}\) b) \(T=a-\frac{(b-c)}{speed}\) c) \(T=a+\frac{(b+c)}{speed}\)
• D. \(T=a-\frac{(b+c)}{speed}\)
