A certain truck uses \(\dfrac{1}{12}+kv^2\) gallons of fuel per mile when its speed is \(v\) miles per hour, where \(k\) is a constant. At what speed should the truck travel so that it uses \(\dfrac{5}{12}\) gallon of fuel per mile?
1) The value of \(k\) is \(\dfrac{1}{10800}\)
2) When the truck travels at \(30\) miles per hour, it uses \(\dfrac{1}{6}\) gallon of fuel per mile
