26. if a young man rides his motorcycle at 40 km per hour, he has to spendoper km on petrol and if he rides it at 50 km per hour, the petrol cost rises to10 per km. he has 500 to spend on petrol and wishes to find themaximum distance he can travel within one hour. formulate the data in theform of inequations and draw a graph representing the solution of theseinequations.hint suppose he rides x km at 40 km/hr and y km at 50 km/hr.then, 6x +10y = 500, + 50 < 1,x20, y 20.​
