A car use 40 litres of petrol to travel 340 km. how far will it travel on a full tank of 52 litres?

how many litres of petrol should it use for a journey of 250 km?

​

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

If rt is greater than ba, which statement must be true ?
